Two straight lines that meet at right angles are perpendicular.
It means parallel to level ground, at right angles to the vertical
It depends on the font. In this font there are: 10 capital letters: B E F H I K L P R T 3 lower case letters: f k t
It is a rarefaction.
Capital letters that have right angles depend on the font, but I can find 10:BDEFGHILPRT2 Lower case letters with right angles are:ft
T
M
well
The letters E, F, and L contain right angles measuring 90 degrees
I assume you're talking about the angles that make up the letters. In which case - yes, you're right. If you're not sure where they all are... The five right angles are formed on the letters L & E, the acute angles are formed on the V's and the triangle of the A and the obtuse angles are formed by the 'legs' of the A. There are more angles involved but those you mention are present.
PANT. P has 3 right angles A has 3 acute and 2 obtuse angles N has 2 acute angles T has 2 right angles
Scalene
There is no letter in the alphabet that has an obtuse angle.
3 Angles
... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.
A kite has 4 right angles (all angles of the kite are right angles), since the kite is parallel. If the kite was cyclic, then 2 right angles. And if normal kite, then 0 right angles.
