Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...

Student complete worksheet using the definitions of lines and angle vocabulary. They define the word and follow a direction given on the worksheet such "construct a line." They complete an online tutorial on how to measure angles using a...

Eighth graders engage in a lesson that is concerned with the finding of angles that are found in different two dimensional figures. They compare and contrast exterior and interior angles while also determining the unknown measures of...

In this postulates and theorems activity, students explore a concept map containing information about angles and sides, alternate interior angles, and diagonals of a parallelogram.  They use the concept map to prove theorems dealing...

Students rewrite word problems and solve using math. In this word problem lesson, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to answer...

Students analyze midsegments of triangles in this lesson. They use Cabri Jr. software to observe the relationships between interior angles and midsegments of triangles. Specific instructions for creating this lesson in Cabri Jr. are...

In this algebra review lesson, students work review problems to get ready for their exam.  There are 16 worksheets in this booklet.

Eighth graders, using a candy bar, gum, and Twizzlers, demonstrate the effects of deformational forces on the earth's crust. They examine the processes of rock and fossil formation.

Students construct midsegments. In this geometry lesson, students make conjectures and apply properties of triangles to solve problems. They complete an activity on the computer.

Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students create a bridge using engineering and geometric concepts. In this geometry lesson plan, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using problem...

Eighth graders use candy to show the effects of deformation forces on the earth's crust.  For this rock and fossil formation lesson students construct models and simulations to describe and explain natural phenomena.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

The student will verify theorems about angles formed by parallel lines cut by a transversal and apply these relationships to solve problems.

Students are challenged to identify and measure angles created by parallel lines and a transversal as well as complementary and supplementary pairs.

Investigate vertically opposite, corresponding, and alternate angles formed by parallel lines and a transversal using this highly interactive Learn Alberta math. Be sure to follow the link to the printable activities, solutions, learning...
