If triangle has one obtuse angle other two angles are acute.
Since, sum of angles of triangle is 180.
What else can I help you with?
A angle more than 90 degrees is called?
An Angle between 90 degrees and 180 degrees is OBTUSE. NB An angle less than 90 degrees is ACUTE An angles between 180 degrees and 360 degrees is REFLEX.
What is the angle when 3 triangle angles are added together?
The 3 interior angles in any triangle add up to 180 degrees.
If the measures of two angles of an isosceles triangle are 54 and 63 degrees what is the measure of the third?
In an isosceles triangle, two angles are equal. Since the angles provided are 54 degrees and 63 degrees, the equal angles must be 54 degrees. The sum of the angles in any triangle is 180 degrees. Thus, the measure of the third angle is calculated as follows: 180 - 54 - 54 = 72 degrees.
What is the vertex of a isoscles triangle that is 9 degrees more than the base angle?
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.
If an isoceles triangle has angles of 20 degreesand 80 degreees what is the measure fore third angle?
The 3rd angle is 80 degrees
Can you draw an obtuse triangle?
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).
If two of a triangle angles measure 42 degrees 48 degrees how would you classify that triangle?
acute , obtuse obtuse or right angle
Can a triangle have 1 obtuse 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.
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.)
Why is it impossible for a triangle to have more than 1 obtuse angle?
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.
What is the difference between a rectangle and a obtuse triangle?
Angles obtuse in on angle is over90 degrees rectangle has 4 angles at 90 degrees.
Can a triangle have 3 obtuse angles?
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.
How do you describe an obtuse triangle angles?
An obtuse triangle has 1 obtuse angle and 2 different acute angles whereas the 3 angles add up to 180 degrees.
What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
What is the rule for an obtuse triangle?
One angle must be over 90 degrees (an obtuse angle), and the other two angles under 90 degrees (acute angles). ^-^
Does a triangle have 3 obtuse angles?
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
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.
