Why are isosceles right triangles similar?
Two others must be equal since a triangle is isosceles, that is they are equal to 45^o each. So, any right isosceles triangle has angles 90^o, 45^o and 45^o. According to one of theorems of similarity, two triangles are similar if two angles of one correspondingly equal to two angles of another.

If two triangles are congruent, are they similar? Please …

 · Yes, they are similar. For two triangles to be similar, it is sufficient if two angles of one triangle are equal to two angles of the other triangle. Note that if two angles of one are equal to two angles of the other triangle, the tird angles of the two triangles too will be equal. If two triangles are congruent then all corresponding sides as well as corresponding angles of one triangle are

Interactive help to prove the triangle proportionality theorem. A transversal is a line that intersects two or several lines. Theorem: A transversal that is parallel to one of the sides in a triangle divides the other two sides proportionally. Proof: All you need to know in order to prove the theorem is that the area of a triangle is given by \[A=\frac{w\cdot h}{2}\]
