Can an equilateral triangle be acute?
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
Is a triangle with two congruent legs always a 45-45-90 triangle?
No. The triangle is an isosceles triangle and the angle between the equal sides can be any angle greater than 0° and less than 180°.
If The shortest side of an isosceles triangle is 23 cm less than twice as long as the other sides The perimeter of the triangle is 41 cm Find the lengths of the three sides?
x+x+(2x-23)=414x-23=414x=64x=16x=16(2x-23)=9
A triangle with all angles measuring less than 90 degrees?
A triangle with all angles measuring less than 90 degrees?That's an 'acute' triangle.
What is the perimeter of 42 Meters and length?
The perimeter of a rectangle is 42. Meters. The length of the rectangle is threemeter less than twice the width.Mar
If the total angle of a triangle is 180 degrees what should be the total perimeter of a triangle?
The sum of the 3 interior angles of any triangle ... no matter how large or small ... is always 180 degrees. This rule has no connection to the perimeter of the triangle. The perimeter may be one inch, less than one inch, 10 miles, more than 1,000 miles, etc., and the sum of the interior angles is always the same 180 degrees.
Could an isosceles triangle have a perimeter of 12cm and area of 12cm2?
No. The maximum are is attained when it is equilateral and that is less than 7 cm2
Each of the two congruent sides of an isosceles triangle is 8 inches less than twice the base the perimeter is 74 inches what are the measurements for all the three sides of the triangle?
69
How can a scalene triangle be acute?
When an angle of the scalene triangle is less than 90 but the other two are always more.
Is the oxygen less at high altitudes?
Yes. Air is less dense at higher altitudes, so the oxygen is at a lower concentration.
What is the perimeter of a 35 ft x 80 ft triangle?
If 35 ft and 80 ft are two sides of the triangle, the third side must be more than 45 ft and less than 115 ft. So the perimeter is between 160 and 230 ft.
What is the perimeter of a right angle triangle when its base is 2.75 cm less than its height and 5.5 cm less than its hypotenuse?
Use Pythagoras' theorem and the quadratic equation formula to find the dimensions of the triangle. Dimensions: hypotenuse 13.75 cm, height 11 cm and base 8.25 cm Perimeter: 13.75+11+8.25 = 33 cm
Can an equilateral triangle be acute?
Yes. Acute angle is less than 90°. 60° which is less than 90°, can make an equilateral triangle .
In general what is true about places at higher altitudes?
They have cooler temperatures than places at lower altitudes.
Is an equilateral always an acute triangle?
Because each of its equal interior angles are less than 90 degrees.
Why do jet airplanes fly at high altitudes?
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
Is a triangle with two congruent legs always a 45-45-90 triangle?
No. The triangle is an isosceles triangle and the angle between the equal sides can be any angle greater than 0° and less than 180°.
