FINAL EXAMINATION in Math 2 (Fall 2024)

Front

If x and y are in direct proportion, what is the formula to find y when given x?

Back

y = kx, where k is the constant of proportionality.

Front

What is the definition of a hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

How do you calculate the cosine of an angle in a right triangle?

Back

cos(θ) = adjacent side / hypotenuse.

Front

What are the zeros of a quadratic trinomial?

Back

The zeros are the values of x that make the trinomial equal to zero.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, indicating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

How do you find the value of y when x is given in a direct proportion problem?

Back

Use the formula y = (k * x), where k is found from the initial condition.

Front

What is the relationship between the sides of a right triangle and the Pythagorean theorem?

Back

Front

What is the significance of the angle in determining triangle congruence?

Back

Angles help determine congruence through criteria like ASA (Angle-Side-Angle) and AAS (Angle-Angle-Side).

Front

What is the quadratic formula used for?

Back

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.
