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.
What is the total angle measure of isosceles triangle?
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
One acute angle of a right triangle measures 20 degrees what is the measure of the other acute angle?
70 degreesA right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.180 - 90 leaves 90 for the other two, and 90 - 20 = 70
If two of a triangle's angles measure 42 degrees and 48 degrees how would you classify that triangle?
It's important to remember that a triangle's angles will always total 180 degrees. 180 - 42 - 48 = 90. The last angle is 90 degrees, so this is a right triangle.
What is the measure of the vertex angle of an isosceles triangle if the base angles measure 56 degrees?
If each base angle is 56°, then the vertex angle is 68°.If both base angles combined total 56°, then the vertex angle is 124°.
How many degrees measure total of angle in triangle?
The total number of degrees in a triangle is 180. this will not change no matter what type of triangle it is. (obtuse, acute, right angle, etc)
What is the total angle measure of a triangle?
180 degrees
In a triangle 2 angles have measures of 45 degrees angle and 85 degrees angle What is the measure of the third angle in this triangle?
50 degrees. 45 and 85 add up to 130 and in a triangle there are 180 degrees in total in a triangle. So subtract and you get 50 degrees.
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.
What is the measure of angle A.?
The total sum of all angles in any triangle is 180 degrees.
What is the total angle measure of isosceles triangle?
The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
How much degrees does an equilateral triangle have?
Total, the triangle has 180 degrees, and each angle has 60 degrees.
One acute angle of a right triangle measures 20 degrees what is the measure of the other acute angle?
70 degreesA right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.180 - 90 leaves 90 for the other two, and 90 - 20 = 70
Two angles of a triangle measure 15 and 85 degrees. What is the measure for the third angle?
The internal angles of a triangle always total 180º. So 180º - (15º + 85º) = 80º.
A right triangle has a 50 angle. What is the measure of the third angle?
40 degrees ! The internal angles of any triangle always total 180 degrees. Since you already know two angles (50 & 90) - the difference is 40.
What is the measure of a base angle of an isosceles triangle if the vertex angle measures 38 and each of the two congruent sides measures 21 units?
The measure of each base angle in an isosceles triangle can be calculated by dividing the total angle sum by the number of base angles, i.e., (180 - vertex angle) / 2. In this case, each base angle of the isosceles triangle would measure (180 - 38) / 2 = 71 degrees.
If two of a triangle's angles measure 42 degrees and 48 degrees how would you classify that triangle?
It's important to remember that a triangle's angles will always total 180 degrees. 180 - 42 - 48 = 90. The last angle is 90 degrees, so this is a right triangle.
