Question

Define triangle classify the triangle on the basis of measures of their angle .​

Answer 1

Answer:

A three sided polygon is called a triangle. On basis of measure of the angles, triangles can be classified into :-

Acute triangle (where all angles are less than 90⁰)

Right triangle (where one angle is 90⁰)

Obtuse triangle (where one angle is more than 90⁰)

Answer 2

Answer:

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

Area: ½ × base × height

Perimeter: sum of side lengths of the triangle

Number of vertices: 3

Number of edges: 3

Internal angle: 60° (for equilateral)

Sum of interior angles: 180°

Line of symmetry: 3

Types of Triangles Based on Angles ( 3 types)

1) Acute-Angled Triangle (all 3 angles are less than 90 degree)

2) Right-Angled Triangle (1 angle measures 90 degree)

3) Obtuse-Angled Triangle (1 angle measures more than 90 degree)
