The other 2 angles will be acute and the 3 angles altogether will add up to 180 degrees
The other two angles are A and (60-A) where 0<A<60.
The 3 interior angles in any triangle add up to 180 degrees.
Its 3rd angle is 180-125 = 55 degrees
The isosceles triangle will have a top angle of 66 degrees and two equal base angles of 57 degrees which all add up to 180 degrees.
The 3rd angle is 80 degrees
If Y is the right angle then the third angle is indeterminate. Otherwise it is 90 - Y degrees.
Yes, its a triangle that has one obtuse angle (an angle over 90 degrees) and two acute angles (angles that are les that 90 degrees).
acute , obtuse obtuse or right angle
A triangle can only have 1 obtuse angle. Obtuse - greater than 90 degrees. Since a triangles 3 angles add up to 180 degrees, only 1 angle can be obtuse. Right triangle 90 degrees and 2 - 45 degree angles. Perfect? triangle has 3 - 60 degree 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.)
There are three angles in a triangle that amount to 180 degrees. If one of these angles was 91 degrees (an obtuse angle) then the sum of the other two angles must be 89 degrees.
No, a triangle can't have more than 1 obtuse angle because all the angles have to equal 180 degrees, and an obtuse angle is larger than 90 degrees. if it had more than 1 obtuse angle, the angles wouldn't equal 180 degrees and you wouldn't be able to make a third angle.
Angles obtuse in on angle is over90 degrees rectangle has 4 angles at 90 degrees.
An obtuse triangle has 1 obtuse angle and 2 different acute angles whereas the 3 angles add up to 180 degrees.
One angle must be over 90 degrees (an obtuse angle), and the other two angles under 90 degrees (acute angles). ^-^
An isosceles triangle
cannot because a triangle has to have 180 degrees i.e. obtuse angled triangle has one obtuse angle acute angled triangle has three acute angles
A triangle with angles 103 degree, 20 degree, and 57 degree is called
