Here is a list of topics we are covering on the Unit 2 test:

• Triangle Congruence (SSS, SAS, ASA, AAS, & HL)
• Writing triangle congruence statements
• Classifying Triangles in the Coordinate Plane using distance formula
• Classifying Triangles by angles and sides
• CPCTC
• Equilateral & Isosceles Triangles

What do you want more practice with before our test on Wednesday?

Classify the triangle. Check ALL that apply!

Find the side lengths in order to classify this triangle.

Given the vertices of a triangle are at (-3,0), (0,3), (3,0), find the length of each side to classify this triangle.

Given that P(-4, -2), Q(-2, 2) and R(5, 1) are vertices of a triangle, calculate the length of each side to classify this triangle.

Given a triangle with vertices at X(-3,1) Y(-3,5) and Z(4,1), find the length of each side. What is the length of XY?
