There are four main types of angles: right angles, acute angles, obtuse angles, and straight angles. Right angles are like corners and measure 90°. Acute angles are smaller than 90°. Obtuse angles are larger than 90°, but less than 180°.
How do you measure an angle without a protractor?
To measure an acute angle without a protractor, start by drawing a vertical line connecting the 2 rays of the attitude to form a right triangle. observe that the angle formed by way of the adjacent side of the triangle and the opposite side measures 90 degrees. next, measure the length of the adjacent side to locate the run
How do you find the degree of an angle in a circle?
You can find the area of a sector of a circle if you recognize the attitude among the two radii. a circle has a complete of 360 tiers all the manner around the middle, so if that important angle figuring out a area has an attitude measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all of the way around.
