As long as you maintain the aspect ratio (width : height), yes - all angles in the image remain the same.
The reason comes from the way an angle is computed in a rectangular coordinate system - it comes in the very end to the division of two segments. Their length change, but since the division factors out the enlarging factor the ratio remain the same.
What else can I help you with?
Why do the angles stay the same if you enlarge or reduce a figure?
Because the figures are said to be similar to each other and retain the same angles
When you enlarge or reduce a figure what are the features that stay the same?
the angles stay the same but the lenght of the sides change.
When you enlarge or reduce a figure what features stay the same?
When you enlarge or reduce a figure, the angles between the lines in the figure will remain the same. The ratio of the lengths of corresponding sides will also remain the same. Additionally, the shape of the figure will generally stay the same, although its size will change.
Are similar triangles always congruent?
No, congruent triangles are always similar but similar triangles and not always congruent. Imagine that similar triangles can be created on a copy machine enlarge and shrink the image, turn it, even turn it over, the angles remain the same. A congruent triangle must be exactly the same as the original. Hope this helps!
Describe the image of a dilation with a scale factor of 1?
With a scale factor of 1, the image is exactly the same size as the original object.
Image of a not regular octagon?
A octagon is a octagon without the same angles as the others.
True or false - The angles in an enlarged shape are always the same as the corresponding angles in the original shape?
True
Do the angles created from an angle bisector have to add up to be the same degree as the original angle?
The two angles created will add up to the original angle that has been bisected.
What are transformations that result is an image that is the same shape and size as the original?
They are translation, reflection and rotation. An enlargement changes the size of the image.
What is definition of image in math?
The figure that results from some transformation of a figure. It is often of interest to consider what is the same and what is different about a figure and its image EX: original Image
How can you determine the scale factor of a dilation by looking at a segment and its image?
Every part of the original scales by the same scale factor. By using a segment of the original you will determine the scale factor by dividing the length of the image by the length of the original.
Which transformation will create an image that is not congruent to the original?
An enlargement but the angle sizes will remain the same.
