Are opposite sides parallel on a triangle?
Never, there are no true "opposite sides" on a triangle as each side intersects the other two at a point. Were two of the lines parallel, the triangle would be missing a point and would not be a closed shape.
If a triangle has a 50 degree angle what are the measure of the two other sides?
Then the other two angles would add up to 130 degrees because there are 180 degrees in a triangle.
What is it called when two sides of a triangle are congruent the angles opposite these sides are congruent?
An isosceles triangle
What is the largest angle of a triangle with sides of 14 cm 8.5 cm and 9 cm?
The largest angle of the triangle will be opposite its largest side and by using the Cosine Rule it works out as 106.23 degrees.
How many sides are perpendicular in a right triangle?
Two sides and they meet each other at 90 degrees.
What are the sides other than the hypotenuse of a triangle called?
opposite and adjacent
Is a right triangle can be isosceles?
Yes. Only if the other two angles of the right triangle are congruent and each equal 45 degrees. Then using the isosceles triangle theorem, you know that the two sides opposite the angles are congruent.
If an isosceles triangle has on side that's sixty degrees what are the other sides?
You cannot have an isosceles trinangle with 60 degrees sides
The isosceles triangle theorem states that if two sides of a triangle are congruent then the opposite those sides are?
The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
Are opposite sides parallel on a triangle?
Never, there are no true "opposite sides" on a triangle as each side intersects the other two at a point. Were two of the lines parallel, the triangle would be missing a point and would not be a closed shape.
How do you get opposite side of right triangle?
The answer depends on what information you do have about the other sides and angles.
What is the perimeter of a triangle when side 14.5cm is opposite angle 57 degrees and has another angle of 71 degrees?
Using the trigonometry sine rule the other sides of the triangle are 16.35cm and 13.62cm so it follows that its perimeter is 14.5+16.35+13.62 = 44.47cm
If two sides in a triangle are congruent then their opposite angles are?
Their opposite angle are equal and all 3 angles will add up to 180 degrees
Can a right triangle have three acute angles and three equal sides?
No, a right angled triangle cannot have three acute angles because an acute angle is less than 90 degrees and a right angled triangle has one angle of exactly 90 degrees (which is what right angled means, equal to 90 degrees).Also, because the triangle has a right angle (of 90 degrees) it cannot have three equal sides; it can have two equal sides but the side opposite to the right angle (the hypotenuse) will always be longer than either of the other two sides.
Does Triangle has three equal sides?
Not all. Only equilateral triangles have. Equilateral triangles have equal sides and 60 degrees on each corner of the triangle. Other triangle need not have equal sides.
What are the opposite angles in a triangle to its sides of 22cm and 62cm and 48cm?
Using the cosine rule in trigonometry the opposite angles to the given dimensions are 17.9 degrees, 120 degrees and 42.1 degrees respectively.
Which is the opposite and adjacent sides in a triangle?
Each triangle has three sides and three vertices. The opposite side of a triangle is the side that is not adjacent to the specified vertex. The other two sides are adjacent sides to the specified vertex. Circular definition? Yes - Here is the formal definition... Given a triangle with vertices A, B, and C, the side AB is adjacent to the angles ABC and BAC, and it is opposite to the angle ACB.
