We are continuing our study of geometry. So far, we have covered the types of angles (acute, right, obtuse, straight), types of figures (rays, lines, line segments, points), relationships (parallel, perpendicular, intersecting) and identifying triangles based on the lengths of their sides (equilateral, isosceles, scalene). Today's focus was on identifying triangles based on the measure of their interior angles (acute, obtuse, right) and combining them.
For example let's say we have a triangle that has sides measuring 13 cm, 13 cm, and 7 cm and has interior angles of 68°, 68°, and 44°. Two of the sides are congruent (the same) and one is different. Also with the angles, two of them are the same and one is not. All of the angles are less than 90°. This makes it an acute isosceles triangle.
