What is the definition for an acute triangle?
An acute triangle is a triangle with all angles acute (for example, a triangle with angles 64 ,36, and 80). An acute angle is an angle less than 90 degrees. Also, all angles in a triangle MUST sum to 180 degrees.
What is the angle sum of the sizes of the acute angles of a right angled triangle?
A right angle triangle has a 90 degree angle and two acute angles and the 3 angles add up to 180 degrees
What shape has 2 right angles 2 acute angle?
No shape does. If a shape has four angles, the sum of the four angles is 360°. If two are right angles, their sum is 2 x 90° = 180°, leaving 360° - 180° = 180° for the two remaining angles. An acute angle is less than 90°, so the sum of two acute angles is less than 90° + 90° = 180°, but in this shape their sum must be equal to 180°; thus no shape can exist. If one angle is acute and the other is obtuse, then their sum can be 180° and the shape is a trapezium.
Can two angles whose sum is a straight angle be acute?
If you mean a 180o angle, which is represented as a straight line, then no. Two acute angles cannot add up to 180o because an acute angle is less than 90o.
Does the sum of any 2 acute angles have to be an acute angle?
No. An acute angle measures less than ninty degrees, so it is possible to have two angle that when added together that the sum sill equal or exceed 90 degrees.
The sum of two acute angles is something always or never an obtuse?
The sum of two acute angles is sometimes an obtuse angle because, acute angles can measure from 10 to 90 degrees. Two 30 degree angles would both be acute whose sum would only create another acute angle of 60 degrees. But, two80 degree angles would both be acute angle whose sum would only create an obtuse angle.
Can a triangle have 1 obtuse angle and 2 acute angles?
A triangle can have one obtuse angle and two acute angles. The sum of all three angles must equal 180 degrees.
What is the definition for an acute triangle?
An acute triangle is a triangle with all angles acute (for example, a triangle with angles 64 ,36, and 80). An acute angle is an angle less than 90 degrees. Also, all angles in a triangle MUST sum to 180 degrees.
Why do all triangles have acute angles?
A triangle is a three-sided figure with three angles, two or three of which (depending on the triangle) must be acute angles. The sum of all of the angles has to equal 180° - no more, no less. An acute angle is an angle of less than 90°. If one of the angles of a triangle is 90° or more (it is a right angle or obtuse angle) the SUM of the other two angles cannot exceed 180° minus the degree of the first angle. Therefore the two remaining angles must be less than the first angle, which means that they have to be acute angles.
What is the sum of the acute angle measure of a right angle?
The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.
If two angles are complimentary and if one angle is acute then the other angle is what kind of angle?
Well, if one angle is acute then the other one has to be acute. This is because the definition of complimentary angles is the sum sum of the angles has to add up to 90 degrees. So therefore, the angle has to add up to 90 degrees.
Which shape has only two acute angles?
"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse
Can a triangle have a right angle and an acute angle?
No A right angle has 90 degree A triangle has 180 degreeYes, a right triangle has one right angle and two acute angles. The sum of the acute angles is 90°.
What triangle has a right angle and 2 acute angles?
an isocelesANS2:Any triangle that has one right angle will have 2 acute angles. An acute angle is less than 90 degrees and the sum of all angles in a triangle is 180 degrees. The sum of the other two angles would have to add to 90 degrees so they would both have to be less than 90 degrees.
What is the angle sum of the sizes of the acute angles of a right angled triangle?
A right angle triangle has a 90 degree angle and two acute angles and the 3 angles add up to 180 degrees
Why Do triangles have 2 acute angles?
The sum of all three angles is 180 degrees. If there are not two acute angle then there are two (or more) angles that are 90 degrees or more. So those two angles sum to 180 degrees of more and so the third angle must have a negative measure - and that is not possible.
Does An Acute Triangle Have Three 90 Degree Or Less?
The sum of the angles of a triangle is 180 degrees so it cannot have three 90 degrees. An acute angle is an angle less than 90 degrees. An acute triangle is one in which all the angles are acute.
