What is the angle between two parallel lines?
the angle between parallel lines is undefined, or it can be either 0 or 180 degrees, or any multiple of 180 degrees.
What are the rules for parallel lines?
Parallel lines are lines that never cross each other – they keep the same distance apart from each other.
- When two lines intersect, the opposite (X) angles are equal:
- On parallel lines, alternate (Z) angles are equal:
- On parallel lines, corresponding (F) angles are equal:
What is a zero angle?
A zero angle (0°) is an angle formed when both the angle’s arms are at the same position. Illustration: ∠ RPQ = 0° (zero angle) Acute Angle. An acute angle is an angle that is more than 0° but less than 90°.
Which side of XYZ is the longest?
Angle Z in the given triangle is the largest angle and therefore, the side opposite to this angle is the longest side of the triangle. Hence, XY is the longest side in the given ΔXYZ.
Which angle is largest AB or C?
1 Expert Answer Largest angle is opposite the longest side. C is opposite side AB. C is largest angle. The law of sines says the ratio of the sine of an angle to the side opposite that angle is a constant.
What angle is opposite the longest side?
The hypotenuse is always the longest side in a right triangle because it is opposite of the largest angle, the ninety degree angle.
Which angle is the smallest in this triangle?
57 degrees
Which is the smallest triangle?
Isosceles triangles have two sides the same length and two equal interior angles. Therefore there can be two sides and angles that can be the “largest” or the “smallest”.
Which is the shortest side in right angle triangle?
In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.
What is the length of the side of a triangle?
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.
What is so special about a right triangle?
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an “angle-based” right triangle.
Which set of sides will make a right triangle?
Which set of sides could make a right triangle? Explanation: By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.
Does 5/12/13 make a right triangle?
What is a 5 12 13 Triangle? The 5 12 13 triangle is an SSS special right triangle with the ratio between its side lengths as 5, 12, and 13. It is a common Pythagorean triple that is worth memorizing to save time when dealing with right triangles. The other common SSS special right triangle is the 3 4 5 triangle.
