Is there any such thing as an obtuse right triangle?
No. A obtuse angle cannot be a right triangle- it is so wrong that it can't even be a left angle (While true, this part is of course, a joke...).There are two ways we name our triangles: using angles and how long the angles' sides are. The angles: there are three. The measurements: there are also three.The measurement triangles (aka. how long the angles and sides are) come in three types: the equilateral, the isosceles, and the scalene.The equilateral triangle has angles the measure sixty degrees and all sides measure the same length.The isosceles triangle has two sides that measure the same length, but one side has a different measurement. Same thing with the angles.The scalene triangle has all sides a different length with all sides a different measurement for the angles.The angled triangles work on three angles: the acute, the right, and the obtuse.The acute triangle's "A" point to its "B" point's angle is an angle that is acute.The right triangle's "A" to its "B" is a right angle...And the obtuse triangle's "A" to its "B" is an obtuse angle.Right angles and obtuse angles are way different...Right angles measure ninty degrees while obtuse angles measure more than ninty degrees but less than one hundred eighty degrees.Therefore, there is no such thing as an obtuse righttriangle.
How can you classify triangles using angles and using sides?
Using angles and sides:All three angles equal. This implies that all three sides are of the same length. The triangle may be known as an equiangular triangle but, more commonly, equilateral triangle.Two equal angles, which implies that two sides are equal. The triangle is an isosceles triangle.All three angles (and therefore sides) are different. This is known as a scalene triangle.Using angles only:If all angles are less than 90 degrees it is an acute angles triangle.If one angle is 90 degrees, a right angled triangle.If one angle is greater than 90 degrees then an obtuse angled triangle.
What is the perimeter and area of a triangle whose longest side is 162cm when two of its angles are 37.25 degrees and 48.4 degrees?
Using the sine rule in trigonometry the perimeter of the triangle is 381.83 cm and its area is 5956.67 square cm both rounded to two decimal places
What is the perimeter of a triangle if its smallest side is 13.62 mm when two of its angles are 71 degrees and 57 degrees?
Its 3rd angle is 52 degrees which is its smallest angle and opposite to its smallest side and by using the sine rule the perimeter of the triangle works out as 44.45 mm to two decimal places
What is the perimeter and area of a triangle when its longest side is 162cm with angles of 37.25 degrees and 48.4 degrees?
Using the sine rule a/A = b/B = c/B the perimeter of the triangle works out as 382.02 cm with an area of 5965.8 square cm rounded to one decimal place.
