Oh triangle, where are the points that will make your type? Given a line segment, pairs determine the location of a third point to create the six different types of triangles. The teacher provides a jumping off point by leading a...

Beware of the construction zone and watch for duplicating line segments and angles. The lesson plan leads pupils through the construction of congruent of line segments and angles. Class members follow the teacher's directions and then...

Just how old is the tree? Using their knowledge of ratios and the distance formula, pupils determine the age of special trees. They do this by using the ratio of the underground to above ground portions of the tree. Along with finding...

Stretch your knowledge of ratios to the coordinate plane. The interactive allows pupils to set the endpoints of a directed line segment and form a right triangle. Using rubber bands, users visualize the line segment divided into equal...

Navigate your way through a lesson on types of lines. Individuals drag line segments to illustrate paths between pairs of houses on an interactive map. They determine if these line segment pairs are intersecting or parallel.

Can you define that basic figure? Building upon the undefined terms in geometry, the instructional activity defines basic geometry figures. The resource defines line segment, ray, angle, perpendicular lines, and parallel lines.

Create a constructionist approach to constructions. The lesson introduces the concept and tools of constructions. Pupils use worksheets to find a method that will perform the given constructions. The teacher guides the groups and...

Geometry begins with a point. The video introduces the concepts of points, lines, and planes. Using diagrams, the presenter includes how to name the objects along with how to write the names. Previewing the concept of 3-D space ends the...

Do you always divide a line segment at the midpoint? Given the coordinates of the two endpoints of a line segment, pupils find the point that partitions the line segment in a particular ratio. They then show and explain their work used...

Given a line segment and its perpendicular bisector, pupils visualize a triangle with the endpoints and a point on the perpendicular as its vertices. Learners determine the type of triangle formed and provide a justification for the...

Given a certain amount of points, how many line segments can you connect between them? How many close geometric figures can you create? These are the types of questions learners are asked to solve in a assessment-based worksheet.

Let's meet in the middle. Given two points on the coordinate plane, pupils use the interactive to find the midpoint. The interactive provides a graphical display of the midpoint and the midpoint formula with the coordinates of the...

Teach ratios of line segments using an interactive approach. Scholars examine a line segment in the shape of a log and use their knowledge of ratios to divide it into various partitions. As an introductory lesson, the segment has a...

Apply geometry to find the distance as the crow flies. An engaging lesson compares the distance a car must drive to the straight line distance between two locations. Scholars must manipulate a simulation, note the change in distances,...

Distance estimates would be easy if the world were a grid. Scholars work to determine the distance between two structures using a coordinate plane. As an introduction, the lesson focuses on vertical and horizontal distances.

Examine the segment addition postulate through an online simulation activity. An interactive lesson allows scholars to manipulate points and watch as the lengths of segments change. Through their study, they are able to apply the Segment...

Direct your class' attention to directed line segments. The interactive resource allows pupils to create segments with specific endpoints. Scholars plot the initial and terminal points to determine the direction and magnitude of the...

Make points about the definition of a line segment. Scholars draw a line segment and indicate clearly what is the segment. The pupils determine a precise definition of a line segment using the concept of a point.

Translate from action to a definition. Given a point and a directed line segment, learners conduct a transformation. The scholars record the steps they take while performing the transformation. The individuals develop a definition from...

It's a dilation sensation! Have your young mathematicians show what they know using a short, simple formative check about the dilation of a line segment. Geometry scholars try their hand at constructing a dilation, then must describe how...

Scholars demonstrate how to split figures in half. Given a line segment and an angle, pupils construct the bisectors of each figure. They finish by providing explanations on the importance of different steps in each construction.

Class members investigate rectangles on the coordinate plane. They determine the length of line segments in the coordinate plane with the same x-coordinate or same y-coordinate and then solve geometric problems involving perimeter and...

Scholars learn how to find the distance of vertical and horizontal line segments on the coordinate plane in the 19th installment of a 21-part module. The use of absolute value comes in handy.
