A right angle measures an angle exactly 90 degrees, obtuse= more than 90, acute less than 90 degrees. Triangle angles add up to 180 degrees quadrilaterals measure up to 360 degrees. A fraction can be written as a decimal or percent answer. A fraction is not a whole number. The reciprocal is the opposite of that number/ fraction. Pls give brainliest.
