Can a triangle have 2 parallel lines?
A triangle has by definition three intersecting sides. If two of the sides are parallel, they will never intersect, so no triangle can ever be formed.
What is a 155 degree angle?
A 155 degree angle is an angle that measures 155 degrees. It falls between 90 and 180 degrees, which means it's an obtuse angle. So, if you're ever in a situation where you need to identify a 155 degree angle, now you know it's just a fancy way of saying "more than a right angle, but less than a straight angle."
Will the medians of an obtuse triangle ever intersect on the triangle?
Yes. Medians always intersect in a single point, called the centroid, or geocenter.
Is an altitude ever outside a triangle?
Sure. If one of the base angles is more than 90 degrees, then the altitude (height) is outside the triangle. Yes. This only occurs with an obtuse triangle. Because an altitude is a line drawn from a vertex to the opposite side and is perpendicular with that opposite side, it can only occur if it is outside the triangle. Look at the triangle in related links. If you look at the vertex on the top, the only way to draw the altitude would be to draw outside the triangle.
Perimeter of a right angled triangle is 12 cm and its hypotenuse is 5 cm.find the other sides?
If you have ever heard of a 3:4:5 triangle, there's your answer. 3 and 4 The reason this is so, is because 3^2 + 4^2 = 5^2 (9 + 16 = 25) according to the Pythagorean Theorem, and 3 + 4 + 5 just so happens to equal 12.
Could a right triangle ever be an an equilateral triangle?
no. A triangle has total 180 degrees. An equilateral triangle requires all three angle measures to be the same, so every angle HAS to be equal to 60 degrees. A right triangle has 1 90 degree angle and 2 45 degree angles, so it can never be an equilateral triangle.
Is an obtuse angle ever an equilateral triangle?
nope
Could a right triangle ever be an equilateral triangle?
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.NOA right triangle always has a 90 degree angle and an equilateral triangle always has three 60 degree angles, so no.
Can a right triangle be classified as an equilateral triangle?
No not ever because they both have different properties
Can a triangle ever have a right angle and a acute angle?
Yes. If its a right angle there has to be an acute angle.
Could a right triangle ever be equilateral triangle?
No but it is possible for it to be an isosceles triangle with angles of 45, 45 and 90 degrees
When ever a triangle has a right angle one angle measure 90 degrees?
no it does not
Could a obtuse triangle ever be an equilateral triangle?
No.
Is a right angled and a eqilateral triangle the same?
Absolutely not, not ever, nohow! An equilateral triangle has three angles of 60 degrees, a right-angled triangle must have one of 90 degrees.
Could a right triangle ever become an equilateral triangle?
No. Regardless of the size the Hypotenuse (the side opposite the right angle) would always be bigger athn either of the other two sides. It has to be as the sum of its square is always equal to the sum of the squares of both of the other two sides.
Can a triangle be classified as an equilateral triangle?
No not ever because they both have different properties
Could a triangle ever be an equilateral triangle?
Yes and it will have 3 equal sides
