Do all right triangles have acute angles?
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
A triangle with 2 acute angles?
All right angle triangles have 2 acute angles and one 90 degree angle.
Do all triangles have 90 degree angles?
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
What are the kinds of triangles according to measure of their sides and angles?
They are: equilateral, isosceles, obtuse, scalene and right angle triangles
What are the angles in the triangles inside a pentagram?
In a perfect star, the triangles have two 72 degree angles and one 36 degree angle.
Which triangles have a right angle d a or c?
They are the triangles that contain a 90 degree angle and two acute angles
Do all right triangles have acute angles?
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
How do you know the measure of each angle in an equilateral triangle using what you know about equilateral triangles and the degree measure of a circle or a straight angle?
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
A triangle with 2 acute angles?
All right angle triangles have 2 acute angles and one 90 degree angle.
Do all triangles have 90 degree angles?
No, only right angle triangles, but all the angles in a triangle will add up to 180 degrees.
Is a 200 degree angle an obtuse angle?
No, a 200 degree angle is a reflex angle. Reflex angles are angles that measure more than 180 degrees.
What is the angle-side-angle rule?
It is a way to tell if two angles are congruent. The easiest one of these are when you have a 90 Degree angle in there. Just measure the mirroring side of the triangles that touch. Measure two of the angles on each triangle and if everything from both sides are coming out with the same answers then the answer is yes it is congruent.
What are the kinds of triangles according to measure of their sides and angles?
They are: equilateral, isosceles, obtuse, scalene and right angle triangles
What do all right triangles have in common?
All right angle triangles have a 90 degree angle and two acute angles which all together the 3 angles add up to 180 degrees.
What kind of triangle is 25 and a 90 degree angle?
Those triangles with 25 and 90 degree angles are called right angle triangle.
How do you know the angles of triangles?
I could use a protractor to measure the angles. You can also interpret whether the angle's acute,obtuse,or a right angle
