Segment BD is an altitude of triangle ABC. Find the area of the triangle. Triangle ABC with altitude BD is shown. Point A is at 2, 1. Point B is at negative 1, 4. Point C is at 2, 6. Point D is at 2, 4. 7.5 9.5 10 15.
In the diagram shown above, we see triangle ABC and the dotted line through A that is parallel to BC. Since angle A, from the triangle, and angles 1 and 2 form a straight (dotted) line, the sum of their measures is 180Âº. We also know that since the dotted line is parallel to BC that by alternate interior angles. This gives us: Substituting for angles 1 and 2 we have This result is true for all triangles: Summarizing: Theorem: The sum of the three angles in a triangle is always 180Âº. Let's Practice: If two of the three angles in a triangle have measure 34Âº and 72Âº, what is the measure of the third angle? We have 34Âº + 72Âº = 106Âº. Therefore the third angle has a measure of 180Âº - 106Âº = 74Âº . In a triangle ABC, we have .
