Geometry Q1 Review

Front

What is the distance formula in geometry?

Back

The distance between two points (x1, y1) and (x2, y2) is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

How do you translate a point in a coordinate plane?

Back

To translate a point (x, y), add the translation values to the coordinates: (x + a, y + b), where 'a' is the horizontal shift and 'b' is the vertical shift.

Front

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two lines. They are supplementary.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of two perpendicular lines are negative reciprocals of each other. If one line has a slope m, the other line's slope is -1/m.

Front

How do you find the value of x in an equation?

Back

To find the value of x, isolate x on one side of the equation using inverse operations.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the Pythagorean theorem states that a² + b² = c², where c is the hypotenuse and a and b are the other two sides.

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points, creating various angle relationships.

Front

What are alternate interior angles?

Back

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