8th Grade Review

Front

What is the formula to find the length of a missing side in a right triangle?

Back

Use the Pythagorean theorem: a² + b² = c², where c is the hypotenuse.

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

How do you write an equation from a table of values?

Back

Identify the relationship between x and y; for example, if y increases by 3 for every increase of 1 in x, the equation is y = 3x.

Front

What is the value of x in the equation 2x + 4 = 36?

Back

x = 16.

Front

If a map has a scale of 1cm : 4km, how do you find the distance on the map for an actual distance of 52km?

Back

Distance on the map = Actual distance / Scale factor = 52km / 4km/cm = 13cm.

Front

What is the definition of alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What is the slope of the line represented by the equation y = 3x?

Back

The slope is 3.

Front

How do you convert a scale of 1cm : 4km to a ratio?

Back

The ratio is 1:400,000 (1cm represents 400,000cm or 4km).

Front

What is the definition of consecutive angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.
