To determine if a triangle has congruent angles without a protractor, you can use the properties of an equilateral triangle, which has all angles equal to 60 degrees. Alternatively, you can apply the Angle Sum Property, which states that the sum of the interior angles of a triangle is always 180 degrees. If you can show that each angle measures the same through geometric constructions or calculations, then the triangle has congruent angles. Lastly, if you can identify that the triangle is isosceles (two sides equal) and use the Isosceles Triangle Theorem, you can conclude that the angles opposite the equal sides are also congruent.
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
no triangle do not have four congruent angles
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
There are three angles in a triangle but to measure them you would use a protractor.
It will be either isosceles or equilateral. It is equilateral if all of the angles are congruent.
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
A triangle with three congruent angles
no triangle do not have four congruent angles
In an isosceles triangle 2 sides are congruent and 2 angles are congruent. In an equilateral triangle all 3 sides are congruent and all 3 angles are congruent also.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
yes, only the isosceles triangle has two congruent angles. But triangles don't need any congruent angles
no because if an scalene triangle had 2 congruent angles it wouldn't be a scalene it would be a isosceles triangle because an isosceles triangle is the only triangle with 2 congruent angles
Yes, because of the base angles theorem converse: If two angles in a triangle are congruent, then the sides opposite the angles are congruent.
a scalene triangle has no congruent sides or measures.
If it doesn't have congruent angles, it's not an isosceles triangle.
Because the 3 interior angles of any triangle add up to 180 degrees.
