Identifying Quadrilaterals: Angles and Sides

This video tutorial introduces quadrilaterals, focusing on identifying them through angles and sides. It explains right, acute, and obtuse angles, and discusses parallel and perpendicular sides. The video covers different types of quadrilaterals, including rectangles, rhombuses, and squares, highlighting their properties such as congruent sides and right angles. It concludes with an explanation of parallelograms and their characteristics.

What angle is defined as being exactly 90 degrees?

• Acute angle

• Straight angle

• Right angle

• Obtuse angle

Which type of angle is less than 90 degrees?

• Right angle

• Obtuse angle

• Acute angle

• Straight angle

What identifies a side as being parallel in a quadrilateral?

• If it forms a right angle with another side

• If it remains the same distance apart from another side

• If it is longer than the opposite side

• If it is perpendicular to another side

How are perpendicular sides identified in quadrilaterals?

• By forming an acute angle
