What is similar triangle class 10?

Definition of Similar Triangles Two triangles are said to be similar, if. (i) their corresponding angles are equal and. (ii)their corresponding sides are proportional. i.e Two triangles ABC and DEF are similar if. (i) ∠ A = ∠ D; ∠ B = ∠ E; ∠ C = ∠ F; and.

What is the full form of BPT in maths?

Basic Proportionality Theorem (B.P.T) Statement: If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, then the other two sides are divided in the same ratio.

## What is the full form of Cpct in maths?

Answer: Corresponding parts of congruent triangles or cpct is used to denote the relation between the sides and the angles of two congruent triangles. Let’s understand this.

### What is Pythagorean theorem converse?

Is asa test of similarity?

Note: The ASA criterion for similarity becomes AA, since when only one ratio of sides = k, there is nothing to check. Given triangles ABC and DEF, suppose angle CAB = angle FDE is a right angle. Then if |EF|/|BC| = |DE|/|AB| = k.
