A triangle can have two right angles true or false?
false
When two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
this is true
A triangle with sides of lengths 10 24 and 27 is a right triangle true or false?
True because it complies with Pythagoras' theorem.
Does the theorem hold true if the triangle is not a right triangle?
Pythagoras' theorem is only applicable to a right angle triangle in that the square of its hypotenuse is equal to the sum of its two squared sides.
Is it true that a scalene triangle is an isosolese triangle?
False
Is a right-angle triangle has one angle of 90 o true or false?
It is true
Can a triangle have both an acute an a right angle true or false?
It is true because a triangle with a right angle and two acute angles is a right angle triangle.
Is it true or false that the legs are the sides that form the right angle in a right triangle?
It is true and the longest side of a right angle triangle is its hypotenuse.
Is it true or false that an isosceles triangle may have a right angle?
It is true.
Is it true or false that a right triangle can be scalene?
A right angle triangle can be scalene. Such a triangle has one right angle, two other unequal angles and no equal sides
A triangle cannot have more than one right angle true or false?
True
An acute triangle is a triangle that has one 90 degree angle true or false?
False. That is a right (-angled) triangle. An acute triangle has all three angles less than 90o
Is this statement true or falseThe triangle is a right triangle?
false
'True or false Two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle'?
Sounds true to me, all three angles are congruent...
If a triangle has a right angle is it a right triangle?
True.
Is a right triangle acute true or false?
False ------------------------------------ An acute triangle is one in which all angles are acute angles. An acute angle is less than 90°. A right angle is 90°, which is equal to 90° not less than 90° Therefore all the angles of a right triangle are not all acute Thus a right triangle is not an acute triangle.
A triangle is a right triangle if and only if it has a right angle?
True
