I WONDER - How Do I Calculate The Angles In A Quadrilateral?

The video tutorial explains that the sum of angles in a quadrilateral is 360 degrees. It covers the specific case of rectangles and squares, where each angle is 90 degrees. The tutorial also demonstrates how to find the fourth angle if three angles are known, and discusses the property of some quadrilaterals where opposite angles are equal.

What is the total sum of angles in any quadrilateral?

• 180 degrees

• 270 degrees

• 360 degrees

• 450 degrees

What is the measure of each angle in a rectangle?

• 90 degrees

• 150 degrees

• 120 degrees

• 60 degrees

Which of the following is true for the angles in a square?

• All angles are 180 degrees

• All angles are 120 degrees

• All angles are 90 degrees

• All angles are 60 degrees

If you know three angles of a quadrilateral, how can you find the fourth angle?

• Subtract the sum of the three angles from 360 degrees

• Add the three angles together

• Multiply the three angles

• Divide the sum of the three angles by 2

In some quadrilaterals, what is true about opposite angles?

• They are always 90 degrees

• They are equal to each other

• They are complementary

• They are supplementary
