About square, rhombus, rectangle and parallelograms

Hi; I have some few questions to ask;

(1) Are the internal angles of rhombus, square, rectangle and parallelograms equals 360?

(2) When one makes diagonal angles within rhombus is the triangle formed be an isosceles or equilateral?

(3) When one crosses diagonal lines within a square, is the triangle formed be equilateral or isosceles?

Many thanks

Re: About square, rhombus, rectangle and parallelograms

1. Yes, if you add them

2. Could be equilateral but not all the time. Usually isosceles.

3. Isosceles

Thanks Agnashom!

One question left and that is;

When one crosses diagonal lines within a rectangle which triangle is formed?

Isosceles.

Why are you not doing the experiments instead of asking?
