Oh, dude, the altitude of a triangle is always perpendicular to the base. It's like a strict rule in Triangle Land - no slanted altitudes allowed! So, if you're ever lost in the wilderness and need to remember one thing about altitudes, just think "perpendicular or bust."
The base angles are always congruent.

An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.

"The sum of the angles in a triangle equal 180 degrees" is a true statement.
No, it's not true.

True, because the slant height and the altitude, or height, of the pyramid form one leg and the hypotenuse of a triangle withing the pyramid, and the hypotenuse of a triangle is always the longest side- it is not possible for the hypotenuse to be equal to the legs of a right triangle. (It is a right triangle because an altitude is perpendicular to the base of a pyramid.)
