Front

What is the slope of a line that is perpendicular to y = 2x - 7?

Back

-1/2

Front

Which set of angles can form a triangle? 1) 45°, 65°, 70° 2) 150°, 110°, 100° 3) 50°, 50°, 50° 4) 90°, 90°, 90°

Back

Front

What does it mean for polygons to be similar?

Back

Polygons are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the Triangle Congruence Theorem that states two triangles are congruent if all three sides are equal?

Back

SSS (Side-Side-Side) Congruence Theorem.

Front

How can you determine if two lines are parallel, perpendicular, or neither?

Back

Compare their slopes: Parallel lines have equal slopes, perpendicular lines have slopes that are negative reciprocals.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

Front

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

Back

180 degrees.

Front

What is the definition of congruent triangles?

Back

Triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

Front

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the definition of a polygon?

Back

A polygon is a closed figure formed by a finite number of line segments.
