What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, meaning the original figure and the transformed figure are congruent. Examples include translations, rotations, and reflections.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is the sine function in relation to a right triangle?

Back

Front

Back

This equation represents a relationship in a right triangle where 32 degrees is one of the angles, 8.5 is the length of the side opposite to that angle, and x is the length of the hypotenuse.

Front

What is the meaning of P(30) = 350 in the context of baking a pie?

Back

P(30) = 350 means that the oven temperature is set to 350 degrees Fahrenheit, 30 minutes after the pie has been placed in the oven.

Front

What is inverse variation?

Back

Front

If y varies inversely with x and y=10 when x=6, what is the constant k?

Back

Front

How do you find the value of y when x=15 if y varies inversely with x?

Back

Front

What is the relationship between the angle of a ramp and its distance from the base of a step?

Back

As the ramp starts closer to the step, the angle it makes with the ground increases. This is due to the fixed height of the step remaining constant while the base distance decreases.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees. The side opposite the right angle is called the hypotenuse.
