What is the complementary angle of a 50 angle?
40
How do you construct the triangle if its sides are not given and the measures of angles are 50 60 and 70 the radius of the circumcircle is 32?
1) Draw a circle of radius 32 2) Draw a radius (meeting the perimeter at A) 3) Based on the radius, construct an angle at the centre of the circle of 100° - draw a second radius (meeting the perimeter at B) 4) Based on the second radius, construct an angle at the centre of the circle of 120° - draw a third radius (meeting the perimeter at C) Note : the angle between the third and first radii measures 140°. 5) Draw chords joining A to B, B to C, and C to A. The triangle ABC has angles measuring 50°, 60° and 70°. NOTE : The process is based on the Theorem that the angle subtended by an arc at the centre of a circle is twice the angle subtended at any point on the circumference.
'If A 100-degree angle is bisected and then each new angle is bisected what is the measure of the smallest angle formed?
100/2 = 50; 50/2 = 25o
What is the measure of an angle that is the complement of a angle that is 50 degrees?
40 degrees
Which angle measure the closest to a 60 degree?
Acute angle
