Pearson Semester 1R Transformations and Conversions in Geometry

Front

What is a translation in the coordinate plane?

Back

A transformation where all points in a figure move in the same direction for the same distance.

Front

What is the perimeter of a right triangle with sides measuring 15 units, 20 units, and 25 units?

Back

The perimeter is 60 units.

Front

What is the definition of a reflection in geometry?

Back

A transformation that flips a figure over a line, creating a mirror image.

Front

What is the formula for the perimeter of a triangle?

Back

Perimeter = side1 + side2 + side3.

Front

What is the value of x if 2x + 4 = 24?

Back

x = 10.

Front

What is the relationship between parallel lines and angles?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal.

Front

What is the definition of a regular polygon?

Back

A polygon with all sides and angles equal.

Front

How do you find the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the significance of the centroid in a triangle?

Back

The centroid is the point where the three medians intersect and is the center of mass.

Front

What is the definition of congruent figures?

Back

Figures that have the same shape and size.
