3 The student can measure the given angles to within 2 degrees of the actual measurement and identify each angle, with 95% accuracy 2 The student is able to measure the given angles to within 10 degrees, and is able to identify the angles with 95% accuracy 1 Student is unable to correctly measure the given angles and/or identify the angles correctly
If the 3 interior angles of a triangle each measure 60 degrees then it is an equilateral triangle
The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.
any equilateral triangle is also equiangular meaning all three angles in the triangle have the same measurement which is 60 degrees. this is because the sum of the angles in a triangle equals 180. Therefore the equilateral triangle is also acute meaning all three angles measure less than 90 degrees each.
130 degrees
The sum of the interior angles of a triangle add up to 180o. So 180 - (45 + 71) = 64o
180 degrees
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
No. The sum of the three interior angles of a triangle will always be 180 degrees.
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
A right triangle.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.

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.
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°.
If the 3 interior angles of a triangle each measure 60 degrees then it is an equilateral triangle
