What is the measure of the third angle of a triangle if one angle measures 4 inches and the other measures 5 inches?
Angles are not measured in inches, they are measured in degrees. It appears you may be asking about a RIGHT triangle of which two sides measure 4 inches and 5 inches. In such a case, if the hypotenuse measures 5 inches, the third side would measure 3 inches....a 3,4,5 right triangle.
Is a Square 90 degrees?
No, one angle of a square is 90 Degrees. Since there are 4 angles in a square you must multiply the degree of one right angle by 4. Therefore a square actually measures 360 degrees.
If three angles of a quadrilateral are congruent and the average of the measures of two angles of the quadrilateral is 80 which number could NOT be the measure of an angle of the quadrilateral?
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
Calculate the measure of a central angle of a regular onehundred and eighty-sided polygon?
The sum of the interior angles of a regular polygon is 2n-4 right angles where n is the number of sides. If n = 180, then 2n - 4 = 360 - 4 = 356 right angles. Each interior angle therefore measures 356 x 90 ÷ 180 = 178°. The central angle of each segment of this polygon therefore measures 180 - 178 = 2°.
Quadrilaterals with four right angles?
The answer is a rectangle because the angles in a rectangle add up to 360`, since a right angle measures 90`. Then four times 90` (4 * 90`=360`).
