That makes B C D an isosceles triangle and , as a consequence, (1) D B C = C D B. When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:Square all 3 sides.Sum the squares of the 2 shortest sides.Compare this sum to the square of the 3rd side. Figure for the proof. Basic Lesson. But we also know that m2=m3+m 4, so now perform the substitution m2=m1+m4, and so m 2 is larger, and not equal to m1! So say you have an isosceles triangle, where only two sides of that triangle are equal to each other. The distance from point D to the 2 sides forming angle ABC are equal Understanding interesting properties like the same side interior angles theorem and alternate interior angles help a long way in making the subject easier to understand In a triangle, the measure of an exterior angle is equal to the sum of the measures of its two remote interior angles Each exterior angle is Proof.
