Question

Define:1) ACUTE ANGLE
2) RIGHT ANGLE
3) OBTUSE ANGLE
4) COMPLEMENTARY ANGLE
5) SUPPLEMENTARY ANGLE
6) ADJACENT ANGLE
7) ANGLES OF LINEAR PAIR
8) VERTICALLY OPPOSITE ANGLES
9) TRANSVERSAL ​

Answer 1

1) acute angle has more than 0° and less than 90°

2) right angle has equally 90°

3)angle which has more than 90 degrees and less than 180 degrees

4)complementary angle : when two angles equal to 90 degrees

5)supplementary angle: when two angles equal to 180 degrees

6)Adjacent angle: angles which are side by side

7)when two angles equal to 180 degrees when a line divides it :linear pair

8)the angles make up 360 degrees

9)if a line passes through two un parallel lines then it is a transversal

Answer 2

Answer:

1. Acute Angle :- angle which is less than 90°.
2. Right angle :- angle which is 90°.
3. Obtuse angle:- angle which is more than 90°.
4. Complementry angle:- sum of angle is 90°
5. Supplementry angle:- sum of angle is 180°.
6. Adjacent angle:-Adjacent angles can be a complementary angle or supplementary angle when they share the common vertex .
7. Angle of linear pair:-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
8. v.o.a :- Vertically Opposite Angles are the angles opposite each other when two lines cross.

9. Transversal:- a transversal is a line that passes through two lines in the same plane at two distinct points.
