All angles are right angles or a triangle has four sides?
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
A triangle with all angles less than a right angle?
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
Do scalene triangles have three different angles?
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
How many right angles triangle has?
a triangle can have only one right angle because the sum of all the three angles of a triangle has to be 180. so if there are more than one right angles, the sum of the angles will exceed 180 and hence the plane figure will no longer be a triangle
All angles are right angles or a triangle has four sides?
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
Does a right angled triangle is one angle always a right angle?
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
Why cant a right triangle be an equilateral?
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
A triangle with all angles less than a right angle?
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
Do scalene triangles have three different angles?
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.
Is an equilateral triangle all right angles?
No, an equilateral triangle as three 60 degree angles.
Why isn't some right triangles the same as equilateral triangles?
-- All three sides of an equilateral triangle are the same length. It's impossible for the sides of a right triangle to all be the same length. -- A right triangle must have a right angle in it. All three angles of an equilateral triangle are the same size. It's impossible for all 3 angles in a triangle to all be right angles.
What of kind of angles are the other two angles of the triangle?
If it is an equilateral triangle all the angles would be 90 degrees or right angles
How many right angles do a right triangle have?
The most right angles a triangle can possibly have is 1. Any more than that, and it has to be a quadrilateral.
Number of right angles in a triangle?
0 or 1. A right triangle has one right angle. All other triangles have zero right angles.
A figue has 2 right angles and 3 line segments is this a triangle?
No, not with two right angles. All the angles in a triangle add up to 180, you have that in two angles.
Do all of the angles on a right angled triangle have to be the same?
No a right angled triangle consists of two acute angles and one right angle
