how are the odd numbers arranged Pascal's Triangle?

I think it has something to do with their angles all adding up to 360 degrees! If you take the internal angle measure of a hexagon (150 I think) and add it up to the 90 degrees in a square and the 60 degrees in an equilateral triangle, you get 360! so it all works out. But squares and hexagons can only tessellate with equilateral triangles so bear that in mind. I think it has something to do with their angles all adding up to 360 degrees!

You can't calculate any angle if all you know is one side of the triangle.

Any right angle triangle can have only one 90 degree angle within it

The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.

The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.

Height will be h=base*tan(angle).

It depends what you need to calculate. There are various formulas for this. It is a branch of mathematics called trigonometry.

The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.

A = 1/2(base)(height)
