What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What type of triangle has two sides of equal length?

Back

An isosceles triangle has two sides of equal length.

Front

How do you find the median of a set of numbers?

Back

To find the median, arrange the numbers in ascending order and select the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Front

What does mode mean in statistics?

Back

The mode is the value that appears most frequently in a data set.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but keeps its shape, using a scale factor.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is the formula for finding the median of a data set?

Back

1. Arrange the data in ascending order. 2. If the number of values (n) is odd, median = value at position (n+1)/2. If n is even, median = average of values at positions n/2 and (n/2)+1.
