Are congruent triangles similar?

Congruent Triangles When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there. read more

If two triangles are congruent, then they will have the same area and perimeter. If two triangles are similar in the ratio \(R\), then the ratio of their perimeter would be \(R\) and the ratio of their area would be \(R^2\). read more

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. read more
