Is it possible to make a triangle with 2 right angles?
No you cannot make a triangle with two right angles. In all triangles the sum of the angles is always 180°. Also all triangles have three angles. If there are two right angles, you already have 180° and cannot have another angle to complete the triangle.
Can a triangle have two angles?
No, a triangle cannot have two angles. Triangles always have three sides and three angles that add up to 180 degrees.
Does an acute triangle have obtuse angles?
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.
Why can a right triangle have only on right angle?
A triangle is composed of 180 degrees. Two right angles = 180 degrees, the total number for all angles in a triangle. Thus a triangle can not have more than one right angle. l____________l <------ This is what two right angles look like, as you can see it cannot ever be a triangle.
What kind of Triangle two equal sides 3 equal angles?
There cannot be a triangle which has 2 equal sides and 3 equal angles. The number of sides and angles which are equal must be the same: 0, 2 or 3.
This triangle has no equal sides and 4 right angles?
A triangle cannot have four angles.
How do you find the hypotenuse of a triangle that has no right angles?
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
Is it possible to make a triangle with 2 right angles?
No you cannot make a triangle with two right angles. In all triangles the sum of the angles is always 180°. Also all triangles have three angles. If there are two right angles, you already have 180° and cannot have another angle to complete the triangle.
How do you know that a triangle cannot have 4 acute angles?
A triangle has three angles; any more angles would result in a non-triangular figure.
What is the sum of two angles of the triangle?
all of the angles in a triangle add up to 180 but i cannot help you because the two angles could be anything?
What figure cannot have congruent angles?
Scalene triangle
Is two angles of a scalene triangle congrunent?
No, they cannot be.
Can you draw a triangle with three different angles?
Yes, as long as they all add up to 180 degrees. A triangle cannot have 2 right angles. A triangle with three different angles is called a scalene triangle.
Can a triangle have 2 abtuse angles?
No, a triangle cannot have more than one obtuseangle.
Which type of triangle have 2 equal sides and angles are all equal?
There cannot be such a triangle.
How do you find the hypotenuse of triangle?
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
Does a triangle have two right angels?
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
