a triangle where at least two sides are congruent | isosceles triangle |
a triangle where all angles are congruent | equiangular triangle |
a segment whose endpoints are a vertex and the midpoint of the opposite side | median |
in a triangle, the point of concurrency of the medians. (center of gravity) | centroid |
in a triangle, the segment connecting the midpoints of two sides | midsegment |
the circle is inside the triangle and touches each of the 3 sides | inscribed in |
a triangle where all sides are congruent | equilateral triangle |
a triangle where one angle is 90 degrees (one right angle) | right triangle |
a triangle where one of the angles is obtuse | obtuse triangle |
a triangle where none of the sides are congruent | scalene triangle |
a triangle is both equilateral and equiangular | regular triangle |
