Can two polygons be congruent if one has a right angle and the other does not?

yes
===================
2nd Opinion:
No.
"Congruent" means the same size and shape. In order to accomplish that, all
corresponding sides and angles must be equal. Your description rules that out.

If the hypotenuse and an adjacent angle of a right triangle are congruent to the corresponding hypotenuse and angle of another right triangle will the two triangles be congruent?
Yes.
What are four ways you can prove two right triangles are congruent?
1. The side angle side theorem, when used for right triangles is often called the leg leg theorem. it says if two legs of a right triangle are congruent to two legs of another right triangle, then the triangles are congruent. Now if you want to think of it as SAS, just remember both angles are right angles so you need only look at the legs.2. The next is the The Leg-Acute Angle Theorem which states if a leg and an acute angle of one right triangle are congruent to the corresponding parts of another right triangle, the two right triangles are congruent. This is the same as angle side angle for a general triangle. Just use the right angle as one of the angles, the leg and then the acute angle.3. The Hypotenuse-Acute Angle Theorem is the third way to prove 2 right triangles are congruent. This one is equivalent to AAS or angle angle side. This theorem says if the hypotenuse and an acute angle of a right triangle are congruent to the hypotenuse and an acute angle of another right triangle, the two triangles are congruent. This is the same as AAS again since you can use the right angle as the second angle in AAS.4. Last, but not least is Hypotenuse-Leg Postulate. Since it is NOT based on any other rules, this is a postulate and not a theorem. HL says if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
Does a right angle triangle have a face?
No. Polygons cannot have faces.
What is a triangle with a right angle but no congruent sides?
That is simply called a right triangle.
Can a right triangle have congruent angles?
yes because it is of course a right angle
Does a right angle have 3 congruent angle?
No
What is the hypotenuse angle theorem?
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
The LAtheorem says that two right triangles will be congruent if they have a congruent and a congruent leg?
The leg-angle congruence theorem says if one leg and an acute angle of one right triangle are congruent to one leg and an acute angle of another right triangle, then the two right triangles are congruent.
What 2d shapes dont tessalate?
A tessellation of congruent regular polygons can occur only when the internal angle of the polygon in question is equal to a factor of 360. So, for example, the internal angle of a square is equal to 90 degrees (a right angle), which divides equally into 360 four times. A regular tessellation can only occur with triangles, squares, and hexagons. Therefore, any other polygons do not tessellate by themselves.
What polygon has no right angle?
There is only one regular polygon which contains right angles - this is a square. None of the other regular polygons from 3 sides and upwards has a right angle.
Are two right triangle similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes
What does the hypotenuse-angle theorem say?
If the hypotenuse and an acute angle of a right triangle are congruent to the correspondingparts of another right triangle, then the triangles are congruent.
If the hypotenuse and an adjacent angle of a right triangle are congruent to the corresponding hypotenuse and angle of another right triangle will the two triangles be congruent?
Yes.
'True or false Two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle'?
Sounds true to me, all three angles are congruent...
Is a right angle and it supplement congruent?
Yes, they are.
