COPY IN SPIRAL. 2 WAYS TO NAME AN ANGLE : 1.BY LEG, VERTEX, LEG VERTEX LETTER MUST BE IN THE MIDDLE. QRSSRQ R Q S R 2. BY VERTEX ONLY. ONLY THE VERTEX LETTER. R

Things you need to know: COPY IN YOUR SPIRAL. A circle has 360° Straight angle: 180° Obtuse angle: 91° to 179° Right angle: exactly 90° Acute angle: 1°-89° Supplementary angles: 2 or more angles that add to 180 ° ADJACENT Supplementary angles: 2 or more angles that add to 180° and share a common vertex and side. Complementary angles: 2 or more angles that add to 90 ° ADJACENTcomplementary angles: 2 or more angles that add to 90° and share a common vertex and side..

EXAMPLES: Complementary Angles: Two or more angles whose sum is = These angles are complementary

ADJACENT Complementary Angles Two or more angles that share a common vertex and side -whose sum is A B C DE AEB+ BEC+ DEC 30° =90°

EXAMPLES Supplementary Angles Two or more angles whose sum is These 3 angles are supplementary = 180

ADJACENT supplementary angles Two or more angles that share a common vertex and side whose sum is A B C D E F AFB + BFC + CFD + DFE = What is the measure of CFD?

Triangle angles are supplementary. ALWAYS. Because all 3 angles will ALWAYS add to 180°. COPY IN SPIRAL: NOW YOU MAY CLOSE YOUR SPIRAL AND WORK ON THE PRACTICE WORKSHEET..
