Answer 1

180 degrees

Question 2

Sum of circles angle

Answer 2

360 degrees

Question 3

Sum of square and rectangles angles

Answer 3

360 degrees

Question 4

Find the hypotenuse on right angled triangle

Answer 4

Pythagoras theorem (edit later with actual expotents)

A^2 + B^2 = C^2

Question 5

Area of a triangle

Answer 5

Area = (Base x Height)/2

Question 6

Area of Circle

Answer 6

Area = Pi r^2

Edit to look neat later

Question 7

Answer 7

Circumference = 2 Pi r

OR

Pi D

(Edit to look neat)

Question 8

Congruent means

Answer 8

Same as each other.

E.g. - congruent angles , lines, shapes etc.

Question 9

Opposite angles

Answer 9

When angles are opposite they’re congruent (equal)

Question 10

When 2 parallel lines are intercepted by another line….

Answer 10

In the top 4 angles:

Top and bottom angles (Y) congruent
Left and right angles (X) congruent.

The bottom 4 angles are identical to these angles.

ALSO: X+Y = 180 (think parallel line)

Vertice =

Answer 11

Corners
