Triangle Sum and Area Practice

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of all angles in a triangle is 180°.

Front

If one angle of a triangle measures 60° and another measures 73°, what is the measure of the third angle?

Back

The third angle measures 47°.

Front

How do you calculate the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its three sides: Perimeter = a + b + c.

Front

What is the relationship between the angles and sides of a triangle?

Back

In a triangle, larger angles are opposite longer sides, and smaller angles are opposite shorter sides.

Front

How do you find the measure of a missing angle in a triangle?

Back

To find a missing angle, subtract the sum of the known angles from 180°.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length * width.

Front

If a rectangle has a length of 10 cm and a width of 4 cm, what is its perimeter?

Back

The perimeter of the rectangle is 28 cm (Perimeter = 2 * (length + width)).

Front

What is the significance of the base and height in calculating the area of a triangle?

Back

The base and height are perpendicular to each other and are used to determine the area of the triangle.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90°.
