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.)
Does an isosceles triangle have a angle greater than 90?
It can. An example of an isosceles triangle without any angles greater than 90 would be an equilateral triangle, with all angles equalling 60 degrees. An example with an angle greater than 90 would be a triangle with angles of 100 degrees, 40 degrees and 40 degrees. You couldn't have an isosceles triangle with 2 angles greater than or equal to 90, as all the angles sum to 180 degrees.
What is the measure of the base angles of an isosceles triangle whose vertex angle has a measure of 50 degrees?
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
Two angles in a triangle measure 48.3 degrees and 33.6 degrees. What is the measure of the third angle in the triangle?
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
What triangle has angles that measure 46 degrees 90 degrees and 44 degrees?
A right triangle.
If two angles of a triangle each measure 45 degrees what is the third angle?
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
All angles in a triangle equal 60 degrees?
If the 3 interior angles of a triangle each measure 60 degrees then it is an equilateral triangle
What would the exterior angle of a triangle measuring 75 degrees be?
A triangle can't measure 75 degrees. A measure in degrees applies to angles, not to polygons such as triangles. In a triangle on a flat surface, the sum of angles is 180°.
How much degrees does a scalene triangle measure?
The sum of the angles of any triangle is 180 degrees.
What is the measure of the angles in a right triangle?
90 degrees
What is sum of the measure of the angles in a triangle is?
180 degrees
Is it possible for the angles of a triangle to measure or 180 degrees?
The 3 interior angles of any triangle add up to 180 degrees
