Corresponding angles must be equal; in this case, that would be angle f. To prove that the two triangles are equal, you would have to prove that at least another pair of angles is also equal, for example, angle b equal to angle d. Or prove some other facts, like the ratio between certain corresponding sides.
What else can I help you with?
What conclusion can you make about the angle in a right triangle?
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
What can you use to measure angles other than a protractor?
A ruler. Add a line to make the angle into a triangle, measure the sides and use trigonometry.
Why is it possible to make an issocles triangle from to right angled triangles?
Because 1 angle will measure 90 degrees and the other 2 angles will each measure 45 degrees
Can you make a triangle with 1 obtuse angle 1 acute angle and 1 right angle?
No.
What is the measure of the third angle of a triangle if the other two angle measures are 60 degrees?
The three internal angles of a triangle always add up to 180 degrees.Two angles of 60 degrees make 120 degrees, leaving a further 60 degrees.
What conclusion can you make about the angle in a right triangle?
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
If two angles of a triangle each measure 54 What is the measure of the third angle?
Well, honey, the sum of all angles in a triangle is 180 degrees. So if two angles are already 54 degrees each, the third angle would be 72 degrees to make up the total. It's basic math, darling.
What can you use to measure angles other than a protractor?
A ruler. Add a line to make the angle into a triangle, measure the sides and use trigonometry.
A triangle has an angle of 108 wich is twice the measure of another angle in the triangle what sre the measures of the 3 triangles?
108 degrees, 54 degrees and what ever it take to make 180. 18 degrees.
If a triangle has one acute angle is the triangle acute?
yes, it only needs one acute angle out of the three to make it an acute triangle.
Why is it possible to make an issocles triangle from to right angled triangles?
Because 1 angle will measure 90 degrees and the other 2 angles will each measure 45 degrees
Can you make a triangle with 1 obtuse angle 1 acute angle and 1 right angle?
No.
What is the measure of the third angle of a triangle if the other two angle measures are 60 degrees?
The three internal angles of a triangle always add up to 180 degrees.Two angles of 60 degrees make 120 degrees, leaving a further 60 degrees.
Which triangle is the only triangle that has perpendicular lines?
The Right Triangle. Perpendicular lines make a right angle.
What kind of triangle does a rectangle make with a diagonal?
right triangle ( triangles with a right angle)
How do you tell if 2 sides and an angle make a non-right triangle?
If it has an obtuse angle
What figure is formed when two line segments meet?
triangle * * * * * What? Two lines can make an angle, but how can they make a triangle?
