slide1. 10/26 WORKBOOK WARM UP Exploring Interior Angles of Triangles–
Open your workbooks to P. 351 EXPLORE: A-C!!!<br>
slide2. 7.1 INTERIOR & EXTERIOR ANGLES OBJECTIVE I can verify theorems about triangles, including the sum of interior angles. (G.6D)<br>
slide3. Triangle Sum Theorem The sum of the interior angles of a triangle is 180.<br>
slide4. TRIANGLE SUM THEOREM PROOF<br>
slide6. EXPLORING INTERIOR ANGLES OF POLYGONS<br>
slide8. POLYGON ANGLE SUM THEOREM The sum of the measures of the interior angles of a convex polygon with n sides is:
(n – 2) 180°<br>
slide9. I DO, YOU WATCH Determine the unknown angle measures.
A) For the nonagon shown, find the unknown angle x°.<br>
slide10. I DO, YOU HELP Determine the unknown angle measures in this pentagon.
6)<br>
slide11. YOU DO, I HELP P. 355 #S 7 & 8<br>
slide12. EXTERIOR & REMOTE ANGLES Exterior Angle – The outside angle of a triangle
Remote Angles – Interior angles not adjacent to the
exterior angle<br>
slide13. EXTERIOR ANGLES THEOREM The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.<br>
slide14. EXTERIOR & REMOTE ANGLES<br>
slide15. REFLECT #9! P. 356 Determine the measure of each exterior angle. Add them together. What can you say about their sum? Explain.<br>
slide16. I DO, YOU WATCH Determine the measure of the specified angle.
A) For angle B<br>
slide17. I DO, YOU HELP Determine the measure of the specified angle.
B) Find m∠PRS.<br>
