If a triangle is isosceles, then…
two sides and two angles are congruent
If a triangle is isosceles, then it means that it has two sides that are of equal length. Therefore, it will also have two angles that are of equal measure. The third angle of the triangle will be different from these two angles, and in general, it will form an obtuse angle if the isosceles triangle has one acute angle and one obtuse angle, or it will be an acute angle if the isosceles triangle has two acute angles.
Additionally, the line segment that connects the midpoints of the two equal sides of an isosceles triangle will be perpendicular to the base of the triangle, and it will also bisect the base. This property is known as the perpendicular bisector theorem.
In summary, an isosceles triangle has the following properties:
– Two sides of the triangle are equal in length.
– Two angles of the triangle are equal in measure.
– The third angle of the triangle is either obtuse or acute, depending on the configuration of the triangle.
– The line segment connecting the midpoints of the equal sides is perpendicular to the base and bisects it.
