Choose the best answer. What are some reasons you would use an acronym? FGHI is a rhombus. The diagonals of a rectangle have equal lengths. Be careful naming the triangles. An acronym is a word formed from the first letters of a phrase.

Therefore the two triangles are congruent by SAS. J The triangles are not congruent. Using the information about the queen-post truss given above, prove each statement on a separate sheet of paper. A rectangular piece of cloth 15 centimeters long is cut along a diagonal to form two triangles. ASA Steps 1, 4, 5 5. What is the area of the other plate?

One sandwich has a side length of 2 inches. To show that ED GF, look for a pair of angles that are congruent. Download ppt ” Triangle Congruence: One angle pair is congruent, because they are vertical angles. SAS Steps 2, 4, 3 5. Practice C Write paragraph proofs for Exercises 1 and 2.

Congruent segments have equal lengths, so the diagonals bisect each other. J The triangles are not congruent. Write a conjecture about the diagonals of a square.

So they set up congruent right triangles. An isosceles trapezoid has one pair of noncongruent parallel sides, a pair of congruent nonparallel sides, and two pairs of congruent angles. Work backward when planning a proof.
