When is a trapezoid isoscels?
When two of its non-parallel sides are congruent
True or false a right triangle cannot be an obtuse triangle?
true
Is this statement true or falseThe incenter of a triangle is equidistant from the sides of the triangle?
true
Is this statement true or falseThe centroid of a triangle is the point of concurrency of the medians of the triangle?
true
If a triangle has a right angle is it a right triangle?
True.
Is a isoscels triangle regular?
An isosceles triangle is not a regular polygon because it has only 2 equal sides but an equilateral triangle is a regular polygon because it has 3 equal sides and 3 equal angles.

In an isosceles triangle does the median to the base bisect the vertex angle?
In the diagram, ABC is an isoscels triangle with the congruent sides and , and is the median drawn to the base . We know that ∠A ≅ ∠C, because the base angles of an isosceles triangle are congruent; we also know that ≅ , by definition of an isosceles triangle. A median of a triangle is a line segment drawn from a vertex to the midpoint of the opposite side. That means ≅ . This proves that ΔABD ≅ ΔCBD. Since corresponding parts of congruent triangles are congruent, that means ∠ABD≅ ∠CBD. Since the median is the common side of these adjacent angles, in fact bisects the vertex angle of the isosceles triangle.
Is it true that a scalene triangle is an isosolese triangle?
