Source sentences:
text: An acute triangle has three acute angles, or three angles with a measure of less than 90 degrees.
text: The two angles that are not right will always be acute angles .
text: In an acute triangle, the largest internal angle is acute — less than 90°.
text: Acute triangle- a triangle where all three angles are acute (less than 90 degrees)
text: Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its apex angle is respectively obtuse, right or acute.
text: No, the isosceles triangle can either have two acute angles, or all three can be acute.
text: ; if a triangle has only acute angles, that is, if all the angles of that triangle are less than 90°, then we have an acute triangle.
text: This means that all the angles are acute.
text: This means that the other two angles will be acute.
text: This means, again, that the other two angles will be acute.
text: The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs.
text: All the three angles situated within the isosceles triangle are acute, which signifies that the angles are less than 90°.
text: If all the three angles are acute ( Fig.20 ), then this triangle is an acute-angled triangle; if one of the angles is right ( C, Fig.21 ), then this triangle is a right-angled triangle; sides a, b, forming a right angle, are called legs; side c, opposite to a right angle, called a hypotenuse; if one of the angles is obtuse ( B, Fig.22 ), then this triangle is an obtuse-angled triangle.
text: (all angles are acute)
text: Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute.
text: Since a right-angled triangle has one right angle, the other two angles are acute.
