Prove that the angle sum of any triangle is 180°

I will be philosophical here...

A square is 4 -90degree angles (definition of perpendicular lines)

If we create a diagonal it splits it into two triangles which in result gives us

90degree + 90/2 degree+ 90/2 degree (because the diagonal split it in half and one full 90 by definition of perpendicular lines)

That gives us the beautiful 180 degrees

which is also what humans use to say that they’ve completely changed or did something completely different...

Mysteries of the triangle...

Can someone help me with this please? Thank you!
Finger [1]

Answer:

528 cm²

Step-by-step explanation:

First I would calculate the area of the side rectangles:

20 x 9 = 180 cm²

There are two identical rectangles on both sides so i would x2

180 x 2 = 360 cm²

The area of the middle rectangle:

6 x 20 = 120 cm²

The area of the triangles:

Area of a triangle = (Base x Height)/2

8 x 6 = 48

48 ÷ 2 = 24

There are two identical triangles on the bottom and the top so x2

24 x 2 = 48

Now add all the values up:

360 + 120 + 48 = 528 cm²

I hope this helps!
