## LESSON 4 6 PROBLEM SOLVING TRIANGLE CONGRUENCE CPCTC ANSWERS

Work backward when planning a proof. Two pairs of sides are congruent, because their lengths are equal. So FH and GI are perpendicular. Use the Distance Formula if necessary. Use the Distance Formula to find the length of each side. Part I Continued 4. SAS Steps 2, 4, 3 5. Two triangular plates are congruent. Refer to the diagram of the king-post truss. Practice C Write paragraph proofs for Exercises 1 and 2. Choose the best answer. Example 1 A landscape architect sets up the triangles shown in the figure to find the distance JK across a pond. She jumped about

Refer to the diagram of the king-post truss. Which is a true statement?

Lesskn is the midpoint of BD. 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. Write a flowchart proof. The diagonals of a rhombus are congruent, perpendicular, and bisect the vertex angles of the rhombus.

So they set up congruent right triangles. Feedback Privacy Policy Feedback. The diagonals of a parallelogram bisect each other. An acronym is a word formed from the first letters of a phrase. We think you have liked this presentation. An isosceles trapezoid has one pair of noncongruent parallel sides, a pair of congruent nonparallel sides, and two pairs of congruent angles. Find the width of the river, GH. To show that ED GF, look for a pair of angles that are congruent. Conbruence by Evangeline Armstrong Modified over 3 years ago.
