TrigL11 QuizStar BACK NEXT Basic Facts Continued 3. The length of the third side of a triangle is less than the sum of the lengths of other two sides and greater than the difference of the lengths of the other two sides. When the measure of angle P is close to 0 o the length of JC is close to 3. As the measure of angle P gets close to 180 o then length of JC gets close to 31. While discussing basic facts, we have the following important facts from geometry.
Vertical angles have equal measures.
If angle AOS has measure 40 o then angle ROB has measure 40 o . 2. Angle ABC and angle CDE are known as alternate interior angles . Also, angle FBC and angle GDC are alternate interior angles. In the above drawing, if the measure of angle ABC is 40 o then the measure of angle CDE is also 40 o . Answer 140 o .
