Exterior Angle of Triangle Examples. In this first example, we use the Exterior Angle Theorem to add together two remote interior angles and thereby find the This video shows some examples that require algebra equations to solve for missing angle values. Exterior Angle of a Triangle Worksheets.
Classifying Triangles / Types of Triangles. On these printable worksheets, students will practice identifying and classifying triangles. On some worksheets, they will sort triangles by angle, identifying Acute, Right, and Obtuse triangles.
Help students learn that the angles of a triangle always add up to 180 degrees. Kids are instructed to add up all the angles in each triangle and write down what conclusion they come to.

Apr 18, 2016 · (180 – adjacent interior angle = sum of the two interior angles) Likewise, the difference between 180 and the adjacent interior angle is equal to the exterior angle (because they form a straight line). (180 – adjacent interior angle = exterior angle) Therefore, the two opposite interior angles and the exterior angle must be equal. So to ...
Then, students will work in groups of four to estimate a traingle's angles and area. Explain that this lesson covers two benchmark units, degrees and centimeters. Draw two triangles on the chalkboard, and write the base and height for each: first triangle, height = 732 and base = 1239; second triangle, height = 128 and base = 985.
The interior angle is always supplementary to an exterior angle at that vertex. Try this Adjust the polygon below by dragging the orange dot. Notice how the interior angle and exterior angle always add to 180°, even for a concave polygon . Find the measure of the opposite interior angles of a triangle the exterior angle of which measures 120 degrees and the two opposite interior angles are equal. What kind of a triangle would that be? Answers: x = 100 degrees, y = 150 degrees; Isosceles; No. The exterior angle should be 160 degrees. 75 degrees; 110 degrees; 55 degrees; 11 degrees ...
