Question

maths definition class 7 alternate angles interior angles transversal

Answer 1

alternate means opposite it means one should be on the opposite side of other and interior means inside

Answer 2

Answer:

1. If a straight line intersects two or more parallel lines, then it is called a transversal line. When the coplanar lines are cut by a transversal, some angles are formed. Those angles are known as interior or exterior angles. Alternate angles are shaped by the two parallel lines crossed by a transversal.

Types of Alternate Angles

Based on the position of the angles, the alternate angles are classified into two types, namely

Alternate Interior Angles – Alternate interior angles are the pair of angles on the inner side of the two parallel lines but on the opposite side of the transversal.

 Alternate Exterior Angles – Alternate exterior angles are the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal

2. The angle between adjacent sides of a rectilinear figure is known as Interior angles

3. When a line intersects two lines at distinct points, it is called a transversal.
