Question

Write down the criteria of congruency which one is applied on righta.​

Answer 1

RHS congruence theorem states that, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent. This rule is only applicable in right-angled triangles.

Answer 2

$\sf\huge\bold{Answer:}$

What is congruency?

The quality of being similar is called congruency.

Geometric figures that have the same size and shape are congruent to each other.

Criteria For Congruency(of Right angled triangle) are:-

• RHS Criterion

When right angle, hypotenuse as well as one side of one triangle, are congruent to another triangle.

$\fbox{Note:This case is only possible when triangles are right angled.}$

In∆ABC and ∆XYZ

∠A=∠X [each 90°]

BC=YZ [hypotenuse are equal in length]

AB=XY [the other side]

∆ABC≅∆XYZ

By RHS criteria
