Answer
Figures which have the same shape but it is not necessary that they same size are called similar triangles.
Work Step by Step
Figures which have the same shape but it is not necessary that they have same size are called similar triangles.
Angles which have the same measurement of two triangles are called corresponding angles. Sides which are opposite to these corresponding angles are called corresponding sides. Ratios of the length of corresponding sides are equal.
If the measurement of two angles of one triangle is equivalent to the two angles of the second triangle, then the two triangles are similar.
