Question

in the adjoining figure triangle ABC , P and q are mid points of side ab and bc prove triangle pqr is one fourth of triangle abc

Answer 1

Answer:

We use numerical measurement called degree to measure angles. We use the notation a˚ to denote a degrees. The rays OA and OB are called the sides of the angle and O is called the vertex if the angle. The angle subtended by the rays OA and OB is denoted by ∠AOB.

We know a geometrical instrument called protractor which is used to measure the angles.

We Know, different types of angles:

Straight line angle, right angle, acute angle, obtuse angle, reflex angle, complete angle, adjacent angle, complementary angles and supplementary angles.
