#### Properties of Equality and Congruence: Lesson

What properties of equality also work for congruence? Part of basic geometry playlist, the video relates algebraic properties to their counterparts of congruence. Learners see how the properties mean the same whether with equality or...

Lesson Planet

#### Diagonals to Quadrilaterals

Begin from the inside and work outward. Pupils construct quadrilaterals based upon the descriptions of the diagonals. Pairs then work through several configurations of diagonals and determine the types of quadrilaterals they can form....

Lesson Planet

#### Proving a Rectangle Is a Parallelogram

Take the time to prove what seems obvious. The resource provides pupils a figure of a rectangle, which they use to develop a proof showing that the rectangle is also a parallelogram. Scholars must rely on the definition of a rectangle to...

Lesson Planet

#### Prove Rhombus Diagonals Bisect Angles

What do congruent triangles have to do with diagonals of a rhombus? Given a rhombus, pupils develop a proof showing that a diagonal bisects opposite angles. The learners use what they know about congruent triangles to create the...

Lesson Planet

#### Proof with Parallelogram Vertices

Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional students to frame their responses.

Lesson Planet

#### Isosceles Triangle Proof

Isosceles means two sides are congruent. Given an isosceles triangles, pupils develop a geometric proof showing that the two base angles are congruent.

Lesson Planet

#### Diagonals of a Rectangle

Coordinate the vertices of a rectangle. Pupils use the location of three vertices of a rectangle along the axis to find the coordinates of the fourth vertex. Using the vertices of the rectangle, scholars prove the diagonals are congruent...

Lesson Planet

#### Camping Calculations

At what angle should you pitch your tent? Given a diagram of a tent, pupils find the measure of a missing angle of the tent frame. Individuals use the properties of angles of polygons to determine the measure of two congruent angles in a...

Lesson Planet

#### Cubism

If cubism were a religion, would you follow it? Lower-level tasks focus primarily on counting the number cubes in a structure and relating the number to surface area. As learners progress to higher-level tasks, isometric drawings and...

Lesson Planet

#### Properties of Quadrilaterals

What type of quadrilateral is that? Discover the difference between the types of quadrilaterals. Small groups investigate types of quadrilaterals using geometry software to find their properties. To keep track of the different...

EngageNY

#### Applications of the Pythagorean Theorem

Examine the application of the Pythagorean Theorem in problem-solving questions. Pupils apply the theorem to find lengths when given different scenarios. They finish the 17th installment in an 18-part series by applying the theorem to...

Lesson Planet

#### Square in Square

Challenge the class to devise a method to determine the dimensions of a rectangle inscribed in another rectangle. Pupils make connections between functions and geometry as they examine the area and perimeter of a square or rectangle...

Lesson Planet

#### Quadrilaterals

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...
