Geometry QA#2 Modified Review

Front

What is the translation rule for moving a point (x, y) to (x', y')?

Back

The translation rule is given by (x', y') = (x + a, y + b), where 'a' is the horizontal shift and 'b' is the vertical shift.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines. They are congruent when the lines are parallel.

Front

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

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What does it mean if two angles are congruent?

Back

If two angles are congruent, it means they have the same measure.

Front

How do you classify a triangle based on its sides?

Back

A triangle can be classified as scalene (no equal sides), isosceles (two equal sides), or equilateral (all sides equal).

Front

What is the distance formula for finding the length between two points (x1, y1) and (x2, y2)?

Back

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of a transversal and outside the two lines. They are congruent when the lines are parallel.

Front

What is the definition of a transversal?

Back

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

Front

What is the relationship between the sides of a triangle and its angles?

Back

In a triangle, if two angles are congruent, the sides opposite those angles are also congruent.

Front

How do you determine if a triangle is isosceles using coordinates?

Back

Calculate the lengths of all three sides using the distance formula. If two lengths are equal, the triangle is isosceles.
