When will two right triangles be similar?
To prove that two right triangles are similar, all you need to show is that one of them has one acute angle that's equal to one acute angle of the other one.
Can an acute and obtuse triangle be similar?
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.
What types of triangles have at least two acute angles?
All triangles need at least two acute angles
Do all acute triangles have only one acute angle?
No. All triangles MUST have at least two acute angles.
Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
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.
Can you draw two acute triangles that are not similar?
Yes, you are allowed to draw two acute angled triangles. Acute means less than 45 degrees. - lovelytoes
When will two right triangles be similar?
To prove that two right triangles are similar, all you need to show is that one of them has one acute angle that's equal to one acute angle of the other one.
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
Can an acute and obtuse triangle be similar?
No. Similar triangles have all the same angles. An acute triangle can never have an obtuse angle, so the two cannot be similar.
Two right triangles that are not similar still may have one congruent acute angle in common?
Not so. The two acute angles of a right triangle must add up to 90 degrees.So if the triangles have one congruent acute angle in common, they must alsohave the other acute angle in common, and then they're similar.
Are all acute and right triangles similar?
no
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.
What types of triangles have at least two acute angles?
All triangles need at least two acute angles
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
