Triangle | MCQs

Explanation

The angle sum of a triangle will always be equal to 180°.

The angle sum of a quadrilateral is equal to 360°

And a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral

Its angle measures should be half as well. Half of 360° is 180°

Explanation

Explanation

an isosceles triangle has equal in sides and in equal angle

Explanation

Explanation

Equilateral Triangle Three equal angles, always 60

all sides are of equal length (equilateral), and all  angles are right angles. 

A triangle that has no equal sides and no equal angles is known as a Scalene Triangle

while 

if two sides of a triangle are of equal length, then it is called. Isosceles triangle

Explanation

The area of a triangle inscribed in a circle is given by:

Area = abc/4R

Explanation

A scalene triangle has no equal sides and no equal angles.

All sides and angles are of different lengths and measures.

Explanation

Area = (9 x 12) : 2 = 54 square unit

Explanation

In a triangle, if two angles are congruent, their opposite sides are also congruent (equal in length).

This is a property of isosceles triangles, where equal angles face equal sides.

Explanation

When two triangles have the same corresponding angles, they are said to be similar.

Similar triangles have the same shape but not necessarily the same size, meaning their corresponding angles are equal and their corresponding sides are proportional.
