Triangles A Guided PowerPoint Presentation 5cm 94º 15cm 10cm 1. A SCALENE TRIANGLE and AN OBTUSE TRIANGLE The reason is: there is an obtuse angle at the top part of the triangle, and all three sides have different measurements. Obtuse angle 2. 3in. 3in. The Right Triangle or An Isosceles Triangle This triangle has a right angle and two sides that are congruent. 3. Right again, and also Scalene. Why? The rectangle in the lower left angle makes it RIGHT. Can you see that all three sides are different in length? What could this be? • Two sides are congruent and all the angles are smaller than 90º. 4. It is a scalene triangle and an... Acute Triangle!!!! ? ? ? ? ? ? ? 5. Acute and Equilateral because….. All sides are congruent and all the angles are 60º. The complete triangle on the right has 3 angles. If we cut off two angles and line them up to the third angle, it creates a 180º angle. Remember, three angles of every triangle equal 180º. a b a b What type is this one?? 6. Four sides can’t be a triangle. It has to be a quadrilateral.
