A triangle is the 2D name of a certain shape. A triangle has three sides and, in the case of a right angled triangle, has an angle of 90 degrees in one corner. There are many other names depending on the angles used.
It is an obtuse triangle if its 2 other acute angles are different in sizes.
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
a scalene triangle
right angle triangle
90
An isosceles triangle
It depends on what kind of triangle.
if the triangle was an equilateral triangle, you would have been able to just multiply 45 with 3... but if the triangle was some other kind of triangle, you would have to know the other sides

right angle triangle
An isosceles triangle has two sides of equal length.
If it is an equilateral triangle all the angles would be 90 degrees or right angles
It is an obtuse triangle if its 2 other acute angles are different in sizes.
A right triangle, whose the length measure of the side opposite to the angle of 30 degrees is one half of the length measure of the hypotenuse.
First convert the base to the same kind of units you have defined the area in (but linear); 24 inches. The area of a triangle is half of the base times the height .12 (half the base) times what is 144?12, the height (altitude) of the triangle is 12 inches (one foot).
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
