angles

Explain step by step, Please answer the questions and please don't spam it​

Answer 1

Answer:

an acute triangle, all the angles of a triangle are less than 90 degrees. In an obtuse triangle, one of the angles of a triangle is greater than 90 degrees. In a right triangle, one angle measures 90 degrees and the other two angles are acute.

Answer 2

Answer:

TRIANGLE:---

A triangle is a polygon with three edges and three vertices.

Types of Triangles Based on Sides

According to the lengths of their sides, triangles can be classified into three types which are:

Scalene

Isosceles

Equilateral

Scalene Triangle

A scalene triangle has all side lengths of different measures.

Isosceles Triangle

In an isosceles triangle, the lengths of two of the three sides are equal.

Equilateral Triangle

In an equilateral triangle, all the lengths of the sides are equal.

Types of Triangles Based on Angles

Triangles can be classified into three types with respect to their interior angles which are:

Acute-angled

Obtuse-angled

Right-angled

Acute Triangle

An acute triangle is a triangle whose all the three interior angles are acute.

Obtuse Triangle

Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees.

Right Triangle

A right triangle is a triangle in which one of the angles is 90 degrees.
