Angle Relationships from Math 7

Match the following terms with their correct meanings.

• Supplementary

• Angles sharing a common vertex and a common side. next door neighbors with one “wall” in between

• Complementary

• Angles whose measures add up to 180°

• Adjacent

• Angles whose measures add up to 90°

• Vertical

• Angles opposite each other within intersecting lines. across from each other inside of an “X”

Match the following terms to their appropriate meanings.

• Right

• Greater than 90°m but less than 180°

• Reflex

• Exactly 180°

• Obtuse

• Exactly 90°

• Straight

• Greater than 180° but less than 360°

• Acute

• Less than 90°

• 14°

• 24°

• 104°

Based on the angle diagram shown here, which equation is accurate for determining the value of x?

• 3x + 23 + 65 = 90
