Question

1. how many angles does a triangle have? ____ 3. does a rectangle have more sides or angles? ____

Explanation:

Question 2

Step1: Recall triangle definition

A triangle is a polygon with 3 sides. By the definition of a triangle (a 3 - sided polygon), the number of angles is equal to the number of sides in a polygon (since each side - angle pair is formed at each vertex). So a triangle has 3 angles.

Step1: Recall rectangle properties

A rectangle is a quadrilateral. A quadrilateral has 4 sides and 4 angles (since the sum of interior angles of a quadrilateral is related to the number of sides, and each vertex has an angle).

Step2: Compare number of sides and angles

The number of sides of a rectangle is 4, and the number of angles of a rectangle is also 4. So a rectangle has the same number of sides and angles.

Answer:

3
