The geometric answer is a rectangle but that does not have 13 letters. The answer is NOT a quadrilateral nor parallelogram because neither of them need have 4 right angles.
right angles and straight angles
No, there is only 1 set of parallel lines in the letter M.
There are no right angles in the letter "e".
right (90˚) and 180˚ angles
In the upper-case letter A? I see none, nor in lower case a either.
When two parallel lines are intersected by a transverse line, they form eight angles. You can consider the parallel lines as the horizontal lines of the letter Z and the transversal as the sloped line of Z. Then the two angles in that Z-shape are the Z angles. The transversal for Z-angles can slope either way. It can be proved that Z-angles, properly called ALTERNATE angles, are equal.
_\_________ .a\b _c\d________ .....\ When a line crosses 2 lines, 8 angles are formed. Four are exterior angles - outside the 2 lines, and four are interior angles. These are labelled a, b, c, d in the diagram. a & d are alternate interior angles because they alternate from one side of the intersecting line to the other; b & c are also alternate interior angles. They are also known as "Z-angles" because the top parallel line, the transversal and the bottom parallel line which define the two angles for the letter Z (or a distorted version of it). If angle a = angle d (in which case angle b = angle c as well), the 2 lines drawn horizontally are parallel. If alternate interior angles are equal, the 2 lines are parallel. OR If you know the lines are parallel, then alternate interior angles must be equal. Not the greatest diagram; please ignore the ... but even a lousy diagram helps. And no, you don't use lower case letters for angles but there shouldn't be any confusion.
13 = thirteen.
A thirteen letter word that ends with tending: overextending
There are 3 acute angles and 2 obtuse angles in the letter A.
What is a thirteen letter word for the French and Indian Revolution?
No, the "i" in "thirteen" is not silent. It is pronounced as the diphthong sound "ee" as in "see."
The letter "K"
There is 3 acute angles in the letter M.
As a capital letter M it has three angles
Well,actually,parallel line are lines that has two line segments,going on side by side without meating each other. example: _____________________________ _____________________________ But actually,the letter x is a intersecting line.You see,an intersecting line is a line cross,but making two obtuse,and acute angles.
The letter 'W' has three acute angles.
