Exterior Angle Theorem Guided Notes Digital Activity By Bien Math The guided notes includes definitions, diagrams, and 3 examples including one using expressions as angle measurements. the answer key showing all work is included! the digital activity is a google slides activity with 6 slides using exterior angle theorem as a fill in the blank activity. see the video preview for a sneak peak at these 6 slides. Use the last page of the guided notes resource to bring the class back together, and introduce the concept of how the exterior angle theorem can be used in real life situations, such as in architecture and engineering when designing structures with angles, in navigation when determining directions and angles, or in art and design when creating geometric patterns and shapes.
Exterior Angle Theorem Guided Notes Digital Activity By Bien Math An exterior angle must form a linear pair with an interior angle. this means that the exterior angle must be adjacent to an interior angle (right next to it they must share a side) and the interior and exterior angles form a straight line (180 degrees). if you extend one of the sides of the triangle, it will form an exterior angle. This set of 8th grade math (pre algebra) binder notes provides guided notes for the triangle sum theorem and the exterior angle theorem. the front side of the page is intended to be used as guided or direct instruction, which includes definitions, diagrams, and scaffolded examples. Created by. math minds 101. this note taking activity is a great way to review or teach the interior and remote exterior triangle theorems. problems include vocabulary, finding missing interior angles, finding missing exterior angles, and solving algebraically.a fully worked out answer key is provided. Exterior angle theorem. the exterior angle d of a triangle: equals the angles a plus b. is greater than angle a, and. is greater than angle b. example: the exterior angle is 35° 62° = 97°. and 97° > 35°. and 97° > 62°.

Scroll down the page for more examples and solutions involving the exterior angle theorem. if one side of a triangle is extended beyond the vertex, an exterior angle is formed. this exterior angle is supplementary with its adjacent, linear angle. since the angle sum in a triangle is also 180 degrees, the exterior angle must have a measure equal. Using the exterior angle theorem to solve problems. example: find the values of x and y in the following triangle. solution: x 50° = 92° (sum of opposite interior angles = exterior angle) x = 92° – 50° = 42°. y 92° = 180° (interior angle adjacent exterior angle = 180°.) y = 180° – 92° = 88°.
