3) the measure of a right angle is _________

4) the measure of a straight angle is _________

5) the measure of a obtuse angle is _________

6) the measure of a refixe angle is
_________

7) A triangle having three unequal sides is called a ________


​

Answer 1

Answer:

1.The measure of a reflex angle is greater than 180 degree. The measure of one complete revolution is 360 degree.

2.To measure angles, it is convenient to mark degrees on the circumference of a circle . Thus, a complete revolution is 360° , half a revolution is 180° , a quarter of a revolution is 90° and so forth.

3.In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

4.180°

5.An angle that measures greater than 90° is known as the obtuse angle. The angle measure ranges from 90° to 180°.

6.A reflex angle is the larger angle, it's always more than 180° (half a circle) but less than 360° (A full circle).

7.Scalene. A scalene triangle has three different angles and none of its sides are equal in length.
