SY25 Geometry IA2 (Final) Review A

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: \( A = \frac{1}{2} \times base \times height \) .

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence.

Front

How do you find the measure of a major arc in a circle?

Back

To find the measure of a major arc, subtract the measure of the minor arc from 360 degrees.

Front

What is the relationship between the height of an object and the angle of elevation?

Back

The height can be estimated using trigonometric ratios, particularly in right triangles, where height = distance * tan(angle).

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of a major arc?

Back

A major arc is an arc that is larger than a semicircle, measured by the angle subtended at the center of the circle.

Front

How do you determine if two triangles are congruent using the SSS criterion?

Back

Two triangles are congruent by SSS (Side-Side-Side) if all three sides of one triangle are equal to the three sides of another triangle.

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is given by the formula: \( C = 2\pi r \) , where \( r \) is the radius.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
