no....
a non-right angled triangle.
no....
A rhombus.

"z" has two acute angles a triangle can have 3 acute angles but also will have a angle >= 60degrees acute (also note for every acute angle a obtuse angle is formed the sum of the obtuse and acute angle will = 360) because of this a arrow is the only shape with two acute angles and 1 obtuse
A right angled trapezoid would fit this description.
arrowhead :)
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
well, if your asking if and acute shape is a wide leaned back angle, well then the answer is no. that's and obtuse angle. and acute angle is smaller than 90 degrees and an obtuse angle is larger than 90 degrees.
A trapezium, a kite, a number of miscellaneous quadrilaterals.
An acute angle is an angle of a shape under 90 degrees, an angle over 90 degrees is called an obtuse angle. hope this helps!:D
