If angle A plus angle D equals 90 the angle A and angle D are what kind of angles?
acute
What is Dihedral angle?
It is a solid angle, or an angle in 3-d space.
What is D in the of angle GDA Geometry?
D is the vertex.
What is an acute angle of a shape?
An acute angle is an angle of a shape under 90 degrees, an angle over 90 degrees is called an obtuse angle. hope this helps!:D
What is the relationship between the angle of elevation and the highest point?
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
If angle A plus angle D equals 90 the angle A and angle D are what kind of angles?
acute
Supplements of the same angle are congruent what's the best statement for reason 6 of this proof?
angle B and angle D are supplements, angle B is congruent to angle D, angle A is congruent to angle A, or angle A is congruent to angle C
If angle A plus angle D equal 90 then A and D are what type of angles?
Acute
What is Dihedral angle?
It is a solid angle, or an angle in 3-d space.
What is the measure of an angle complement?
The complement of an angle which measures D degrees, where D must be less than 90, is 90 - D.
ABCD is a quadrilateral in which angle A 40 degrees and angle B 150 degrees. Could ABCD be a parallelogram?
for a+ NEVERIn a parallelogram opposite angles are equal. Thus angle c = angle a = 40o.The sum of all the angles in a quadrilateral is 360o, so:angle a + angle b + angle c + angle d = 360o=> 40o + angle b + 40o + angle d = 360o=> angle b + angle d = 280o.
What type of angle is 62 degrees?
It is an acute angle.
In triangle DEF angle E is 3 times angle D and angle F is 9 less than angle E what is the measure of each angle?
D=27 E=81 F=72
What is D in the of angle GDA Geometry?
D is the vertex.
What are Z and F and C angles?
An 'F' angle is called a corresponding angle, a 'Z' angle is called an alternate angle and a 'C' angle is called a supplementary angle.
In a parallelogram the measure of angle b the measure of angle a by 30 degrees what is the measure of angle d?
105 degrees
What else would need to be congruent to show that abc def by asa?
Angle "A" is congruent to Angle "D"
