Basic Angle Rules

This video tutorial covers basic angle rules in geometry, including angles in triangles, quadrilaterals, on a straight line, around a point, and vertically opposite angles. Each rule is explained with examples, and viewers are encouraged to practice with questions provided at the end.

• 90°

• 360°

• 180°

• 270°

How many degrees do the angles in a quadrilateral add up to?

• 180°

• 90°

• 360°

• 270°

What is the total of angles on a straight line?

• 90°

• 360°

• 270°

• 180°

What is the sum of angles around a point?

• 360°

• 270°

• 180°

• 90°

If two lines intersect, what can be said about the vertically opposite angles?

• They are different

• They are equal

• They are supplementary

• They are complementary
