Classify triangles and find interior and exterior angles of triangles.

null

Acute Triangle: Triangle with three acute angles.

Obtuse Triangle: Triangle with one obtuse angle.

Right Triangle: Triangle with one right angle.

Equiangular Triangle: Triangle where all three angles are congruent (equal).

Isosceles Triangle: Triangle with two congruent sides.

Equilateral Triangle: Triangle with all three sides congruent.

Scalene Triangle: Triangle with no congruent sides.

Interior Angle: Angle inside the triangle.

Exterior Angle: Angle formed outside of the triangle if one side is extended.

Open this Desmos link. Drag the different points of the triangle to create different triangle shapes. What do you notice about the sum of the angle measures? Is it always the same? What is the sum?
Sum = total of all measures added together

The figure shows the measures of various angles of a roof and its supports. Find the measure of ∠1, the angle between an eave and a horizontal support beam. Show or explain how you found it.

Please check your work using the answers posted in Google Classroom. Then complete the following exit ticket problems.

EXTENSION: Classify by its sides and angles. Either use the distance formula to find all three side lengths and the formula for slope to check for right angles OR use desmos like I do in the video and upload a screenshot of your desmos graph showing how you found each side length. Pick two choices, but you must have work or a desmos screenshot to receive credit.
J(1,2), K(-4,0), L(-2,5)
