another triangle, then the two triangles are similar. 7. If a line is parallel to one side of a triangle and intersects the other two sides in two distinct points, then the line separates the two sides into congruent segments. 8. A segment whose endpoints are the midpoints of two sides of a triangle is parallel to the third side of the triangle. 9.
2. Two triangles are similar. The smaller triangle has angles that measure 30, 60, and 90. The larger triangle has two angles that measure 60 and 90.

Congruent Triangles There are five different ways to find triangles that are congruent: SSS, SAS, ASA, AAS and HL. For each pair of triangles, select the correct rule. Similar and Congruent Games Similarity of Triangles Answer questions on the similarity of triangles and two related theorems: Midpoint Theorem and the Basic Proportionality Theorem.
a 2 + b 2 = c 2 where c is the hypotenuse (the side opposite the right angle) a 2 = c 2 - b 2 a 2 = 100 2 - 96 2 a 2 = 10000 - 9216 a 2 = 784 a = 28 # Problem Correct ...

the other. Obviously, the sides of two similar right triangles are different due to the net difference in the size between the triangles. However, their corresponding angles and trigonometric ratios are the same. In what follows, we use the similar right triangles in Figure 7 to illustrate these facts. Figure 7.
