Answer 2

$\LARGE\sf {\underline{\underline\green{Required \: Answer:-}}}$

When two lines intersect, an angle is formed at their point of intersection. The different types of angles based on their measurements are:

1. Acute Angle - An angle less than 90 degrees.

2. Right Angle - An angle that is exactly 90 degrees.

3. Obtuse Angle - An angle more than 90 degrees and less than 180 degrees.

4. Straight Angle - An angle that is exactly 180 degrees.

5. Reflex Angle - An angle greater than 180 degrees and less than 360 degrees.
