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
Does an acute triangle have two congruent sides?
Not every acute triangle has two congruent sides, although some do, in which case they are called isosceles triangles.
What is the hypotenuse angle theorem?
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
What is LA Congruence Theorem?
LA Congruence Theorem says: If one leg and an acute angle of one right triangle are congruent to one leg and an acute angle of another right triangle, then the two right triangles are congruent.
Which shapes have acute angles?
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.
Are acute-angled triangles similar?
Similar in the number of sides but not congruent
Can two right triangles that are not similar still have one congruent acute angle in common?
No, it’s false.
Two right triangles are similar if the acute angles of one triangle are congruent to the acute angles of the other triangle?
yes there similar
If an acute angle of one right triangle is congruent to an angle of a second triangle then are the triangles similar?
true.
'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...
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
Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
What are the four congruence theorems for a right triangle?
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
The LAtheorem says that two right triangles will be congruent if they have a congruent and a congruent leg?
The leg-angle congruence theorem says if one leg and an acute angle of one right triangle are congruent to one leg and an acute angle of another right triangle, then the two right triangles are congruent.
Are acute triangles similar?
Not necessarily. Just because two triangles are both acute doesn't make them similar. They could be similar, but not necessarily.
Does an acute triangle have two congruent sides?
Not every acute triangle has two congruent sides, although some do, in which case they are called isosceles triangles.
It appears from the name of the HL Theorem that you actually need to know that only two parts of two triangles are congruent in order to prove two triangles congruent Is this the case?
No. You can know all three angles of both and all you can say is that the triangles are similar. Or with any pair of congruent sides you can have an acute angle between them or an obtuse angle.
