If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar. JKL ~ XYZ Example 1: Determine whether the triangles are similar. If they are, write a similarity statement. Explain your reasoning. a.) b.) c.) Example 2: Show that the two triangles are similar. a.) Similar Triangles: Congruent triangles have corresponding parts with angle measures that are the same and side lengths that are the same. If two triangles are congruent, they are also similar. Similar triangles have the same shape, but may be different in size. It is possible for two triangles to be similar but not congruent.
squares are similar and all equilateral triangles are similar. From the above, we can say that all congruent figures are similar but the similar figures need not be congruent. Can a circle and a square be similar? Can a triangle and a square be similar? These questions can be answered by just looking at the figures (see Fig. 6.1). Evidently

This problem asks us to find the rate the shadow’s head as it moves along the (stationary) ground, so it’s best to make our measurements from a point that isn’t also moving—namely, from the post. Hence we focus on $\ell$ and aim to compute $\dfrac{d \ell}{dt}$. B. To develop your equation, you will probably use . . . similar triangles.

Types of triangles classified by their sides and angles We can also name triangles using angles and sides at the same time. If a triangle has one right angle and two equal sides, we can call that triangle right isosceles triangle. If a triangle has only acute angles and no equal sides, we can call that triangle acute scalene triangle.
