SY25 Geometry IA2 (Final) Review B

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 it mean to translate a triangle in geometry?

Back

Translating a triangle means to move it from one position to another without changing its shape or size. The coordinates of each point of the triangle change according to the translation vector.

Front

How do you find the area of a shaded region in geometry?

Back

To find the area of a shaded region, subtract the area of the unshaded part from the total area of the shape.

Front

What is the ASA (Angle-Side-Angle) criterion for triangle congruence?

Back

The ASA criterion states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the two triangles are congruent.

Front

What is the sum of the angles in a triangle?

Back

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

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

How do you calculate the area of a triangle with a base of 10 units and a height of 5 units?

Back

Using the formula \( A = \frac{1}{2} \times base \times height \), the area is \( A = \frac{1}{2} \times 10 \times 5 = 25 \) square units.

Front

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is 90 degrees, and the sum of the other two angles is 90 degrees.

Front

What is the formula for the area of a circle?

Back

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

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.
