Step-by-step answer

P Answered by Master △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (1) 1

The angle that can be equal to 90° will be △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (2) or △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (3)

Step-by-step explanation:

△abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (4) has △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (5).

That means, the longest side is △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (6) and the shortest side is △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (7)

As the sum of all angles in a triangle is 180°, then if two angles are 60° and 90°, so the third angle will be: △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (8)

Now, we know that the measure of opposite angle to the longest side is the largest angle.

As here side △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (9) is the longest side, so △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (10) or △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (11) will be the largest angle which is 90°

Step-by-step answer

P Answered by PhD △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (12) 7

∠A = 90°

Step-by-step explanation:

In this question relation between angles a, b and c have been given.

If one angle is 60° then we have to find the angle which measure 90°.

In triangle ABC,

∠A + ∠B + ∠C = 180°

If angle B = 60°

Then ∠A + 60 + ∠C = 180

∠A + ∠C = 180 - 60

∠A + ∠C = 120°

We know ∠A > ∠C

Therefore, ∠A = 90°

and ∠C = 30°

Now the angles of the triangle will be

∠A = 90°

∠B = 60°

∠C = 30°

∠A = 90° will be the answer.

Step-by-step explanation:

When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.

-Triangles ABC and A'B'C' are congruent.

-Angle ABC is congruent to angle A'B'C'. (this is one of the angles of the congruent triangles)

-Segment AQ is congruent to segment A'Q.

Step-by-step answer

P Answered by PhD △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (15) 4

The correct options are;

D. Triangles ABC and A'B'C' are congruent

E. Angle ABC is congruent to angle A'B'C'

F. Segment BC is congruent to segment B'C'

H. Segment AQ is congruent to segment A'Q'

Step-by-step explanation:

The given information are;

The angle of rotation of triangle ABC = 60°

Therefore, given that a rotation of a geometric figure about a point on the coordinate plane is a form of rigid transformation, we have;

1) The length of the sides of the figure of the preimage and the image are congruent

Therefore;

BC ≅ B'C'

2) The angles formed by the sides of the preimage are congruent to the angles formed by the corresponding sides of the image

Therefore;

∠ABC ≅ ∠A'B'C'

3) The distances of the points on the figure of the preimage from the coordinates of the point of rotation are equal to the distances of the points on the figure of the image from the coordinates of the point of rotation

Therefore;

Segment AQ ≅ A'Q'.

Triangle a b c is shown with its exterior angles. line c b extends through point d. line b c extends to form exterior angle that is 135 degrees. angle c a b is 75 degrees. what is m∠abc? m∠abc = 15° m∠abc = 45° m∠abc = 60° m∠abc = 75°

Step-by-step answer

P Answered by PhD △abc has a b c. if one of the angles in the triangle is 60°, name the angle that can be equal to 90°. (16) 39

m∠ABC = 45°

Step-by-step explanation:

See the attached figure.

As shown in the figure

Line C B extends through point D to form the exterior angle that is 135 degrees.

So, m∠ABD = 135°

But m∠ABC + m∠ABD = 180°

∴m∠ABC = 180° - m∠ABD = 180° - 135°= 45°

Also, we should know that

m∠ABD = m∠BAC + m∠ACB

So, m∠ACB = 135° - 75° = 60°

========================================

Very important note:

If we replaced the location of B and C

SO, m∠ABC = 60° and m∠ACB = 45°
