What is always true about the angles of an isosceles triangle?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A B and C is denoted △ABC. In Euclidean geometry any three points when non-collinear determine a unique triangle and simultaneously a unique plane. In other words ther…

What is always true about the angles of an isosceles triangle? All three angles are congruent. At least two of the angles are congruent. The vertex angle is a right angle. The vertex angle is obtuse
All three angles are congruent. At least two of the angles are congruent. The vertex angle is a right angle. The vertex angle is obtuse Since it is given that AB ≅ AC it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other. If m∠B > m∠C then AC > AB because of the triangle parts relationship theorem. For the same reason if m∠B …
What is always true about the angles of an isosceles triangle? all three angles are congruent. at least two of the angles are congruent. the vertex angle is a right angle. the vertex angle is obtuse.
An isosceles triangle is a type of triangle that has two sides that are the same length. The two marked sides are both the same length. The two angles opposite these two marked sides are also the same: both angles are 70°. All three interior angles add to 180° because it is a triangle.
The angles situated opposite to the equal sides of an isosceles triangle are always equal. All the three angles situated within the isosceles triangle are acute which signifies that the angles are less than 90°.
For any isosceles triangle the following six line segments coincide: • the altitude a line segment from the apex perpendicular to the base • the angle bisector from the apex to the base • the median from the apex to the midpoint of the base • the perpendicular bisector of the base within the triangle • the segment within the triangle of the unique axis of symmetry of th…
