Unit 1 & 2 Final Review

Front

What is the Distance Formula used to find the distance between two points (x1, y1) and (x2, y2)?

Back

Front

Calculate the distance between the points (7, 8) and (2, -4).

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If one angle in a triangle measures 76 degrees and another measures 48 degrees, what is the measure of the third angle?

Back

The third angle can be found using: 180 - (76 + 48) = 56 degrees.

What is the Substitution Property of Equality?

Back

The Substitution Property of Equality states that if a = b, then a can be replaced by b in any expression.

Front

If 3x + y = 14 and y = 9, what is the value of x?

Back

Substituting y in the equation: 3x + 9 = 14, thus 3x = 5, so x = 5/3.

Front

What is the Reflexive Property of Equality?

Back

The Reflexive Property of Equality states that any quantity is equal to itself, e.g., a = a.

Front

What is the Symmetric Property of Equality?

Back

The Symmetric Property of Equality states that if a = b, then b = a.

Front

What is the Transitive Property of Equality?

Back

The Transitive Property of Equality states that if a = b and b = c, then a = c.
