☆☆☆☆☆Yes, it has sides that are straight line segments. Exactly one pair of opposite sides is parallel. Polygons do not have curved sides.
A quadrilateral is a parallelogram with four sides. For example: square, rectangle, parallelogram, trapezoid, rhombus, diamond...

No, never. There's more than one way to get at it: -- The angles of an equilateral triangle are all equal. Since the interior angles of any triangle always add up to 180 degrees, the angles of an equilateral triangle are each 60 degrees. There's no right angle. -- A right triangle is a triangle with an interior right angle. An equilateral triangle has three equal angles. If it were a right triangle, each angle would be a right angle. Then: -- the three interior angles would add up to 270 degrees, which is impossible in a triangle; and -- two sides would be parallel to each other, they would never meet, and there could be no triangle. -- The sides of a right triangle satisfy the Pythagorean equation: A2 + B2 = C2. If all three sides were equal, then you'd have (two times the square of a number) equal to (the square of the same number), which isn't possible. -- Remember that the 'hypotenuse' of a right triangle is the longest side. But an equilateral triangle can't have a 'longest' side.
NO
A right triangle always has a 90 degree angle and an equilateral triangle always has three 60 degree angles, so no.

Use the sine ratio:
sine 30 degrees = opposite/hypotenuse
Then:
opposite = 2*sine 30 degrees
Answer: 1 foot
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.

If side BC of an equilateral triangle equals 10, the other two sides will also equal 10. However, in the case of an equilateral triangle ABC, the sides would be AB, BC, and AC. There is no side AD, so it would not have any length.

If it's a right angle triangle then side ac is 10 units in length.
It is a quadrilateral with exactly 2 pairs of parallel sides.
A right triangle has a hypotenuse of 12cm and a leg that is 9cm the other leg would be 7.94. This is a math problem.
No, it is not.
Use Pythagoras' theorem for a right angle triangle to find the length of the 3rd side.
In right triangle ABC, angle C is a right angle, AB = 13and BC = 5 What is the length of AC? Draw the triangle to help visualize the problem.
