Look carefully at the given diagram. Can you notice any congruent triangles?
Pairs of congruent triangles: 1 & 10, 2 & 9, 3 & 8, 4 & 7, and 5 & 6
Practice makes perfect
We are given a figure that contains 10 triangles and asked to indicate which of triangles are congruent. Let's look at the given diagram. Notice that we are asked to assume that segments and angles that appear to be congruent are congruent.
Looking at the diagram we can see that it appears that the figure has an axis of symmetry. Therefore, we can see that there are 5 pairs of triangles that appear to be congruent.
