In this lesson, we will learn how to determine whether an angle in a triangle is acute, right, or obtuse by using the Pythagorean inequality theorem.
Students will be able to
Q1:
In triangle π΄π΅πΆ, (π΄π΅)+(π΅πΆ)<(π΄πΆ)ο¨ο¨ο¨. What type of angle is π΅?
Q2:
In triangle πππ, (ππ)>(ππ)β(ππ)ο¨ο¨ο¨. What type of angle is π?
Q3:
In a triangle π΄π΅πΆ, if (π΄π΅)=(π΅πΆ)+(π΄πΆ)ο¨ο¨ο¨, which angle is the right angle?
