Math 2 Unit 3 Test 2024-2025

Front

What is the measure of angle 2 if it is given that angle 1 is 130°?

Back

Angle 2 = 50° (because angles on a straight line sum to 180°).

Front

If ∆LMK ≅ ∆JMT, what can we conclude about the corresponding sides?

Back

LK ≅ JT, LM ≅ JM, MK ≅ MT (by the definition of congruent triangles).

Front

What are Alternate-Interior Angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines. They are equal when the lines are parallel.

Front

In a 30-60-90 triangle, what is the ratio of the lengths of the sides?

Back

The ratio is 1 : @@rac{{ ext{√3}}}{{2}} : 2 (shortest side : longer leg : hypotenuse).

Front

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

Back

The sum is always 180°.

Front

What is the definition of corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are equal when the lines are parallel.

Front

How do you find the length of the sides in a 30-60-90 triangle if the shortest side is 8?

Back

The longer leg (u) = 8√3 and the hypotenuse (v) = 16.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are always equal.

Front

What is the relationship between Same-Side Interior Angles?

Back

They are supplementary, meaning they add up to 180° when the lines are parallel.

Front

If two angles are complementary, what is their sum?

Back

Their sum is 90°.
