Question:

m.
What could an acute-angled triangle be? Can we define it as a triangle with one acute angle? Why not?
Answer:
If
one of the angles
atleast two angles
all the three angles
of the triangle are
equal to 90°
less than 90°
greater than 90°
, then it is called an
acute angled triangle
right angled triangle
obtuse angled triangle
.
We
can
cannot
define a triangle with one acute angle as acute angled triangle because
every triangle has atmost one angle to be acute
every triangle has atleat one angle to be obtuse
every triangle has atleast one angle to be acute
.
