Question

name the type of the triangle. in triangle ABC M/A=90 degree​

Answer 1

Scalene Triangle: The triangles having distinct sides and angles are called the scalene triangle. Right angle Triangle: If anyone angle of the triangle is 90°, then the triangle is said to be the right-angled triangle.

Answer 2

The triangle ABC is a right angled triangle.

Given :

Triangle ABC

Measure of ∠A = 90º

To find out :

Type of triangle

Solution :

We are given a triangle, in which measure of one angle is given. We have to find out the type of angle.

We all know that A triangle has three angles.

The sum of three angles of an triangle is always 180° .

Now if one of the three angles is 90° then it is called as right angled triangle.

Types of triangles : Based on angles there are three types of triangles.

Acute angled triangle: In acute angled triangle all three angles are less than 90°.

Right angled triangle: In right angled triangle one of the three angles is right angle ie 90°

Obtuse angled triangle: In obtuse angled triangle, one of the angles is obtuse ie more than 90° and less than 180°.

In the given triangle ABC , measure of

∠A = 90º hence the triangle ABC is a right angled triangle.
