GEO S1 Spiral Review #11

Front

What is the relationship between parallel lines and angles formed by a transversal?

Back

When a transversal intersects two parallel lines, the corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

Define congruent segments in geometry.

Back

Congruent segments are line segments that have the same length.

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of the measures of two complementary angles is 90 degrees.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

How do you find the length of a side in a triangle using the Law of Cosines?

Back

The Law of Cosines states that for any triangle with sides a, b, and c, and angle C opposite side c: c² = a² + b² - 2ab * cos(C).

Front

What is the definition of a transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.

Front

Explain the concept of corresponding angles.

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

Define the term 'isosceles triangle'.

Back

An isosceles triangle is a triangle that has at least two sides of equal length.
