MATH 2 - FINAL EXAM REVIEW

Front

Find the measure of the missing angle in a triangle if the other two angles are 45° and 90°. What is the missing angle?

Back

The missing angle is 45°.

Front

Which trigonometric ratio is used to find the adjacent side when the hypotenuse and angle are known?

Back

cos X = adjacent/hypotenuse.

Front

Solve for x in the equation 2x² + 2x - 12 = 0. What are the roots?

Back

The roots are x = 2 and x = -3.

Front

What postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent?

Back

The postulate is SAS (Side-Angle-Side).

Front

Reflect the point (2, -4) over the y-axis. What is the new coordinate?

Back

The new coordinate is (-2, -4).

Front

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

Back

The sum of the interior angles of a triangle is 180°.

Front

Define the Pythagorean theorem. What does it state?

Back

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²).

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

What does the term 'congruent' mean in geometry?

Back

Congruent means that two figures have the same shape and size.

Front

What is the definition of a complementary angle?

Back

Complementary angles are two angles whose sum is 90°.
