Answer 1

Answer:

1. degree

2. congruent

3.hypotenuse

4.linear pair

5. polygon

6. obtuse angle

7. protractor

8. triangle

Answer 2

Answer:

1. Unit of measurement for angles.

⇒ Unit of measurement for angles is degree. Example :- 180°

2. Two geometric figures that are exactly the same.

⇒ Two geometric figure that are exactly the same is called congruent. Symbol :- ≅

3. The side of the triangle that is opposite to the right angle.

⇒ The side of the triangle that is opposite to the right angle is called Hypotenuse.

Formula to find the length of hypotenuse in right angle triangle if the length of other two side is given :-

Hypotenuse^2 = (Side one)^2 + (Side two)^2

4. Two adjacent angles have a sum of 180 degree.

⇒ Two adjacent angles have a sum of 180 degree is supplementary angle.

Complementary angle are those with sum 90°.

5. A shape made from straight lines.

⇒ A shape made from straight lines is Polygon. It is a plane figure/shape made with straight line.

6. An angle greater than 180 degree.

⇒ An angle greater than 180 degree is called obtuse angle.

Angle less than 90 degree is called Acute.

Angle exactly 90 degree is called right angle.

7. A math tool used for measuring or drawing angles.

⇒ A math tool used for measuring or drawing angles is called protector. It start from 0° to 180°.

8. A closed figure formed by the three intersecting lines.

⇒ A closed figure formed by the three intersecting lines is called triangle. Symbol :- Δ
