Sometimes~ Minor arcs have central angles less than 180 degrees because 180 is a semi-circle and above 180 is a major arc. An acute angle is less than 90 degrees, so this is only true sometimes.

How do you find measure of minor arc?
the measure of a minor arc equals the measure of the central angle that intercepts it.
A central angle of a circle is a right angle then what is the measure of the minor arc?
You can draw exactly four of the those right-angled sectors in a circle. The definition of a sector is quoted as "the portion of a circle bounded by two radii and the included arc". The circumference of a circle = 2*pi*radius. The arc of each sector will be 0.5*pi*radius.
How many images will be formed when a candle is placed between two plane mirrors at 40 cm's apart?
The answer depends on the angle between the mirrors. The distance between the mirrors does not, in theory, make any difference. If the angle between the mirrors is x degrees, then the theoretical number of images is (360/x)- 1 which is rounded down. In practice, minor defects in the mirrors, refraction, total internal refraction, absorptions, scattering etc will reduce the number of images.The answer depends on the angle between the mirrors.

Why do diagonals of a kite cross at right angles?
The short answer is: because that is what a kite is. Long answer (although some minor steps have been skipped): Consider a kite, ABCD, where AB = DA and BC = CD Draw the diagonal AC. Then triangles ABC and ACD are congruent (SSS). So angle BAC = angle DAC. Now draw diagonal BD which intersects AC at E. Then triangles ABE and ADE are congruent (SAS) So angle AEB = angle AED. But these angles are supplementary. Therefore they must be right angles.
What is the antonym of minor?
Major is a word. It is the antonym of minor.
Is The central angle of a minor arc is an acute angle?
Not necessarily. It can be obtuse. It cannot, however, be a reflex angle.
Is the central angle of a minor arc an acute angle?
Not necessarily. Only if the minor arc is less than 1/4 of the circle. If the minor arc is more than 1/4 of the circle, then the central angle is obtuse.
What is an arc that lies between the sides of an acute central angle called?
minor arc
Is it true an acute angle inscribed in a circle must intercept a minor arc?
No, because there is no acute angle in a circle.
What is the relation between inscribed angle and central angle of minor arc?
minor arc of cord is half of major arc of same cord
Is the measure of a minor arc equal to the measure of its central angle?
CONGRUENT
If the measure of a minor arc is 155 what is the measure of its central angle?
155
How do you find measure of minor arc?

What is An arc that lies between the two sides of a central angle called?
minor arc
An arc that lies between the two sides of a central angle is called a?
Minor arc
The central angle of a minor arc is than inscribed angle of its corresponding major arc?
This cannot be answered. This does not make any sense.
What is the arc length of the minor arc if the central angle is 150 and the circumference is 31.4?
Minor arc/Circumference = 150/360 Minor arc = 31.4*150/360 = 13.0833...
