An archaeologist draws the triangles to find the distance XY across a ravine. Write a flowchart proof. Use the Distance Formula to find the length of each side. Proving Corresponding Parts Congruent Given: Suggest us how to improve StudyLib For complaints, use another form. What can you conclude?

If you prove that two triangles are congruent, then you can use CPCTC as a justification for proving corresponding parts congruent. Use any form of proof that you want.

Download ppt ” Triangle Congruence: They want to cross the river but decide to find out how wide it is first. Congruent segments have equal lengths, so the diagonals bisect each other.

B All the sandwiches are isosceles triangles with side lengths of 2 inches. ABCD is a parallelogram. To show that ED GF, look for a pair of angles that are congruent. The diagonals of a rhombus are congruent, perpendicular, and bisect the vertex angles of the rhombus.

Be careful naming the triangles. FGHI is a rectangle.
