What conclusion can you make about the angle in a right triangle?
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
The measure of an exterior angle of a triangle is equal to the sum of the measures of its?
two opposite interior angles.
What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 42?
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.
What is the angle measure for a triangle?
The angle measure of a triangle is dependent on the type of triangle (scalene, right, isosceles, or equilateral) and also the measures of the other two angles.In a scalene, none of the angles can be predicted without a protractor because none of the angles are equal.In a right triangle only one angle can be undoubtedly determined, the 90° angle (right angle). Knowing this angle's measure, this only limits the possible angle measures of the other two angles. (They must each be less than 90°, but together sum up to 90°)If you know one of the base angles of an isosceles triangle, by the Isosceles Triangle Base Angles Theorem, the other base angle will be congruent. To find the last angle, add the base angles together and then subtract that number from 180.The only triangle that has angle measures that can be determined just by its name is an equilateral, all angle measures equal 60°.
What is the measure of a base angle of an isosceles triangle if its vertex angle measures 50?
Its 2 equal base angles will each measure 65 degrees
