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.
